Answer: Option A. -> Natural Gas
Answer: (a)
Non-conventional energy, also known as renewable energy, refers to the energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.
Non-conventional energy sources are infinite, natural, and restorable. Natural gas is a conventional source of energy.

Answer: Option A. -> 3500 km
Answer: (a)
Agni-III is an intermediate-range ballistic missile developed by India as the successor to Agni-II. It has a range of 3,500 km- 5,000 km and is capable of engaging targets deep inside neighbouring countries.
The missile’s Circular error probable (CEP) is within 40 meters range, which makes it the most sophisticated and accurate ballistic missile of its range class in the world. Agni III—an intermediate-range ballistic missile—was developed by India as the successor to Agni-II. Designed by the Indian government’s Defence Research and Development Organisation, Agni III is a two-stage ballistic missile that is capable of nuclear weapons delivery.
It was designed and developed by the Advanced Systems Laboratory (ASL), a unit of DRDO, which was formed in September 2001 with its main objective being the development of large-sized rocket motors.
Note: Agni-VI is an intercontinental ballistic missile reported to be in the early stages of development by India. It will be capable of being launched from submarines as well as from land and will have a strike range of 8,000–10,000 km with MIRVed warheads.
Agni-V is a solid-fueled intercontinental ballistic missile (ICBM) developed by the Defence Research and Development Organization (DRDO) of India. It will greatly expand India’s reach to strike targets more than 5,500 km away.
Agni-IV is the fourth in the Agni series of missiles which was earlier known as Agni II prime. Its full range of 4000 km
