Earth's circumference is approximately 40,075 km at the equator. Dividing by 360 degrees gives about 111 km per degree. This is a standard approximation used in geography and navigation. 105 km (B) and 101 km (C) are too small, while 120 km (D) is too large.

The National Housing Bank (NHB) is a subsidiary of the Reserve Bank of India (RBI). It was established in 1988 to promote housing finance institutions and to provide financial and other support to such institutions.

Jupiter is the largest planet in our solar system, with a mass approximately 2.5 times that of all other planets combined. It is a gas giant with a diameter of about 140,000 km, making it significantly larger than Earth, Venus, or any other planet.

Jim Corbett National Park, established in 1936 as Hailey National Park, is India's first and oldest national park. Located in Uttarakhand, it was named after hunter-turned-conservationist Jim Corbett and is famous for its Bengal tiger population.

Tea is commonly referred to as 'green gold' due to its high economic value, especially in regions like Assam and Darjeeling where it's a major cash crop that drives local economies. The term highlights tea's importance as a valuable agricultural commodity similar to how gold represents wealth.

Earth's orbital circumference around the sun is approximately 966 million kilometers. This is calculated based on Earth's average distance from the sun (about 149.6 million km) using the formula for circumference: 2πr, where r is the orbital radius.

Earth's rotational axis is tilted at approximately 23.5 degrees and points toward Polaris, also known as the North Star or Polar Star. This is why Polaris appears stationary in the northern night sky while other stars appear to rotate around it.

Indian currency notes, including the ten rupee note, bear the signature of the Governor of the Reserve Bank of India (RBI). The RBI is responsible for currency management in India, and the Governor's signature authenticates the legal tender.

Desert forests are characterized by xerophytic adaptations including pointed or needle-like leaves that minimize water loss through reduced surface area and transpiration. Broad, dense leaves would lose excessive water in arid conditions and are thus unsuitable for desert environments.

The United States is the world's largest producer of fertilizers, with a well-developed chemical industry that manufactures nitrogen, phosphate, and potash-based fertilizers. While India is a major consumer, the U.S. leads in production capacity and output.

Blue stars are hotter than the sun, with surface temperatures exceeding 10,000 Kelvin compared to the sun's approximately 5,500 Kelvin. Star color indicates surface temperature: blue stars are hottest, followed by white, yellow, orange, and red stars as coolest.

A sudden fall in barometric pressure indicates approaching stormy weather. Low pressure systems are associated with storms, clouds, and precipitation, while high pressure systems bring fair weather. Rapidly dropping pressure signals an approaching low-pressure system or storm front.

Madhya Pradesh has the largest area under forests in India, with approximately 77,700 square kilometers of forest cover. Its central Indian location and diverse geography support extensive forest ecosystems, making it the state with the maximum forest area in the country.

Indra was the Vedic deity associated with rain and thunder, making him one of the most important gods in the Vedic pantheon. He was worshipped as the bringer of rains essential for agriculture and was depicted as wielding the thunderbolt (Vajra) as his weapon.

NSE was incorporated in 1992 as a tax-paying company and started operations in 1994 with wholesale trading in debt instruments. It revolutionized Indian financial markets by introducing electronic screen-based trading instead of the open outcry system used by BSE. The other options are incorrect - 1993 was the year when SEBI was granted statutory powers, and 1988 predates NSE's formation.

The 30-year age limit applies to Rajya Sabha membership, not the Presidency.

The National Development Council (NDC) was established in August 1952 to promote balanced economic development across all states and union territories. It was created following the recommendations of the Planning Commission (which itself was set up in March 1950). 1947 was India's independence year, and 1951 was the year when the First Five Year Plan commenced.

The first metal tools developed during the Chalcolithic period were primarily used for clearing forests and preparing land for agriculture, as early civilizations expanded into new territories. Metal implements were more efficient than stone tools for felling trees and clearing vegetation. While metal tools were also used for pottery and later for wheel-making, the earliest and primary application was land clearance for settled agriculture.

The PIN code system uses a 6-digit number where the first three digits represent the sorting district within a state. The first digit indicates the zone (9 zones in India), the first two digits together indicate the sub-zone, and the first three digits specifically identify the sorting district - the main post office that handles mail for that region. The last three digits identify the specific delivery post office.

Earth rotates on its axis from west to east (counter-clockwise when viewed from above the North Pole). This direction is the same as its revolution around the Sun and is why the Sun appears to rise in the east and set in the west. This west-to-east rotation is a fundamental characteristic of all planets in our solar system, though the speed varies.

Emperor Ashoka conquered Kalinga (modern-day Odisha) in 261 B.C. in a bloody war that reportedly caused over 100,000 casualties. This conquest was a turning point in Ashoka's life - the horror of war led him to embrace Buddhism and adopt the path of non-violence (Dhamma). The Kalinga War transformed him from 'Ashoka the Terrible' to 'Ashoka the Great'.
