BrahMos is the fastest supersonic missile of the world. It is a Mach 3 "fire-and-forget" missile, inducted in all three services of the Indian Armed Forces. Hence, statement 1 is incorrect.

The variants of BrahMos missile include land, ship, submarine and air-launched missiles. BrahMos II, the hypersonic cruise missile, is currently in the developing phase. Hence, statement 2 is correct.

Answer: C

Explanation:

Solid Propulsion uses solid propellants like Hydroxyl-terminated polybutadiene (HTPB) fuel. It is simple, low-cost and reliable. For ex., Prithvi and Brahmos. Hence, pair 1 is correctly matched.

Liquid Propulsion employs liquid fuels (Hydrazine - N2H4, Liq. hydrogen, etc.) and oxidisers (Nitrogen tetroxide - N2O4, Liq. oxygen, etc.). It has higher efficiency and throttle ability. For ex., Agni series and Akash. Recently, India has successfully tested the Agni-Prime missile with solid propellant, making it lighter than other Agni series missiles.

Hence, pair 2 is correctly matched.

Hybrid Propulsion, uses a combination of solid and liquid propellants. For ex., It is used in Brahmos hypersonic cruise missile prototype. Hence, pair 3 is correctly matched.
