Correct option is (2). 

The correct answer is 'Prithvi'. The Prithvi missile was the first missile inducted into the Indian Army (in the 1990s). It is a short-range ballistic missile. Agni is a longer-range missile developed later, Seabird is not a missile system, Pinaka is a multiple rocket launcher system, and Trishul is a surface-to-air missile.

The correct answer is '9km'. Trishul is a short-range surface-to-air missile (SAM) developed by India's DRDO. It was designed to engage aerial threats at short ranges, with an operational range of approximately 9 kilometers. It was part of India's integrated guided missile development program.

Prithvi II is a short-range ballistic missile developed by DRDO with an operational range of approximately 250-350 km. Option D (250 km) is correct as it falls within this range. The other options (200, 500, 750, 1000 km) are outside the actual operational specifications of Prithvi II.

INS Arihant, launched in 2009, is India's first indigenously built nuclear-powered submarine. It marks a significant milestone in India's defense capabilities and nuclear deterrence. INS Chakra was a leased Soviet submarine, while INS Virat and INS Vikrant are aircraft carriers, not submarines.

Project Seabird is the code name for India's largest naval base development at Karwar, Karnataka. It's designed to decongest the Mumbai naval base and provide strategic depth in the Arabian Sea. The other options (Agni, Pinaka, Prithvi, Thrishul) are all missile systems, not naval base projects.

Trishul is India's short-range surface-to-air missile system developed by DRDO as part of the Integrated Guided Missile Development Program. It's designed for air defense against low-flying aircraft and helicopters. Agni is a ballistic missile, Seabird is a naval base project, Pinaka is a rocket artillery system, and Prithvi is a surface-to-surface ballistic missile.

INS Shalki, commissioned in 1992, was the first submarine to be built in India at Mazagon Dock Limited. It was constructed based on technology transfer from Germany. INS Chakra was on lease from the Soviet Union, while INS Virat and INS Vikrant are aircraft carriers, not submarines.

Agni II is an intermediate-range ballistic missile with an operational range of approximately 2,000-2,500 km, making option C (2000-3000 km) the closest correct answer. It's designed for strategic deterrence and can target deep within hostile territory. Options A and B are too short for Agni II (though Agni I has shorter range), while option D is partially correct but option C is more comprehensive.

Akash is a medium-range surface-to-air missile system with an operational range of approximately 25 km, designed for air defense against aircraft, helicopters, and unmanned aerial vehicles. It's part of India's integrated air defense network and can engage multiple targets simultaneously.

The Eastern Army Command of the Indian Army is headquartered at Fort William in Kolkata, West Bengal. It's responsible for defending the eastern border, including the Northeast states and the border with China and Bangladesh. Shimla is the Northern Command headquarters, Pune is the Southern Command headquarters, Lucknow is the Central Command headquarters, and Delhi hosts the Western Command (Army) and Western Air Command.

INS Savitri (note: the question spells it 'Savitri' while the ship's name is INS Savitri) was indeed the first warship fabricated at Hindustan Shipyard Limited in 1990. It's a follow-on vessel of the Khukri class. The other options - INS Virat (aircraft carrier), INS Vikrant (aircraft carrier), INS Shalki (submarine), INS Chakra (submarine) - are either different ship types or built elsewhere.

The Western Air Command of the Indian Air Force is headquartered in New Delhi. It's the largest and most important air command, responsible for defending northern and western India, including the borders with Pakistan and China. The other cities are headquarters for different commands - Kolkata (Eastern), Pune (Southern), Lucknow (Central Army Command), and Shimla (Northern Army Command).

The Central Army Command is headquartered at Lucknow, Uttar Pradesh. It's responsible for the central region of India, including areas facing the northern border. Shimla is the Northern Command, Kolkata is the Eastern Command, Pune is the Southern Command, and Delhi is the Western Army Command (not Western Air Command).

The Western Army Command is headquartered at Shimla, Himachal Pradesh. It's strategically located to defend the western border, particularly Punjab and Jammu & Kashmir sectors facing Pakistan. The other cities host different commands - Kolkata (Eastern), Pune (Southern), Lucknow (Central), and Delhi (Western Air Command, not Army Command).

The Southern Army Command is one of the seven operational commands of the Indian Army. Its headquarters is located in Pune, Maharashtra. Pune is a major military hub with several defense establishments including the Armed Force Medical College and the Intelligence School of Army.

The Intelligence School of the Army is located in Pune, Maharashtra. Pune is home to several key military training institutions including the Armed Force Medical College and serves as the headquarters of the Southern Army Command.

The Nag is a third-generation fire-and-forget anti-tank missile developed by India's DRDO. It has a range of approximately 4 km, though some variants and later developmental versions have extended ranges up to 7 km. The 4 km range represents its baseline operational capability.

Vayu Bhawan is the headquarters of the Indian Air Force and is located in New Delhi. It houses the Air Headquarters and the Ministry of Defence's Department of Defence. The building is situated in the 'R' Block of the Air Headquarters, New Delhi.

The Central Industrial Security Force (CISF) was established in 1969. It was set up to provide security to public sector undertakings and later expanded to cover other critical infrastructure including airports, metro rails, and government buildings. CISF functions under the Ministry of Home Affairs.

Pinaka is India's multi-barrel rocket launcher (MBRL) system developed by the DRDO. It is capable of firing a salvo of 12 rockets in 44 seconds and can destroy targets within a range of 40-60 km. The system is named after Lord Shiva's bow Pinaka. Other options like Agni and Prithvi are ballistic missiles, not rocket launchers.
