1. Consider the following statements:

1. Ballistic missiles are jet-propelled at subsonic speeds throughout their flights, while cruise missiles are rocket-powered only in the initial phase of flight.
2. Agni-V is a medium-range supersonic cruise missile, while BrahMos is a solid-fuelled intercontinental ballistic missile.

Which of the statements given above is/are correct?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 nor 2

Answer: (d) Neither 1 nor 2

Both statements 1 and 2 are incorrect.

Statement 1: Ballistic missiles are not jet-propelled at subsonic speeds throughout their flights. Ballistic missiles are propelled by rocket engines during their flight trajectory, reaching supersonic or hypersonic speeds. They follow a parabolic trajectory, primarily relying on the initial propulsion to reach their targets.

Statement 2: Agni-V is an intercontinental ballistic missile (ICBM), not a medium-range supersonic cruise missile. BrahMos is a supersonic cruise missile, but it is not solid-fueled and it does not have intercontinental range.

Therefore, the Answer:  is (d) Neither 1 nor 2. Once again, I apologize for the earlier incorrect response.
