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

Correct answer: (d) Neither 1 nor 2

Explanation

  1. A

    1 Only

    1 only. Statement 1 reverses ballistic and cruise propulsion.

  2. B

    2 Only

    2 only. Agni-V is a solid-fuel ballistic missile, not a cruise missile; BrahMos is a ramjet cruise missile, not an ICBM.

  3. C

    Both 1 and 2

    Both. Each sentence is inverted.

  4. D

    Neither 1 nor 2

    Neither. Ballistic missiles are rocket-boosted then coast; cruise missiles are jet-powered for most of the flight. Agni-V ≠ cruise; BrahMos ≠ ICBM.

Summary. Official key is (d) neither. A ballistic missile is rocket-powered in boost and then follows a ballistic arc; a cruise missile is typically jet-propelled and guided in the atmosphere. Agni-V is an Indian long-range ballistic missile; BrahMos is a supersonic cruise missile. Both statements swap the families.
