Indian Defence and Strategic Weapons

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.

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.

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.

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.

BrahMos is a supersonic cruise missile developed jointly by India and Russia. While Pokhran is famous for nuclear tests, BrahMos represents India's advanced conventional missile capability.

Nag is India's third-generation anti-tank guided missile developed by DRDO. It is a fire-and-forget missile with top-attack capabilities. Trishul is a surface-to-air missile, Agni is a ballistic missile series, and Shakti is primarily associated with nuclear tests or tactical missiles.
