Answer:(d) Neither 1 nor 2.

Explanation:

Statement 1 states that ballistic missiles are jet-propelled at subsonic speeds throughout their flights, while cruise missiles are rocket-powered only in the initial phase of flight. This statement is incorrect. Ballistic missiles are powered by rocket engines throughout their flight trajectory and can achieve supersonic speeds. Cruise missiles, on the other hand, are jet-propelled and can maintain subsonic speeds throughout their entire flight.

Statement 2 states that Agni-V is a medium-range supersonic cruise missile, while BrahMos is a solid-fuelled intercontinental ballistic missile. This statement is also incorrect. Agni-V is an intercontinental ballistic missile (ICBM) developed by India, capable of delivering nuclear warheads. It is not a supersonic cruise missile. BrahMos, on the other hand, is a supersonic cruise missile jointly developed by India and Russia. It is not an ICBM and has a limited range.
