2. Agni-V is a medium-range supersonic cruise missile, while BrahMos is a solid-fuelled intercontinental ballistic missile.

Correct Answer: Option (d) 

• Cruise missiles are jet-propelled at subsonic speeds throughout their flights, while ballistic missiles are rocket-powered only in the initial (boost) phase of flight, after which they follow an arcing trajectory to the target. Hence, statement 1 is not correct. 
• Agni V is India’s long-range surface-to-surface ballistic missile, which can hit a target with a precision that is 5,000 km away. The BrahMos is a supersonic cruise missile, developed by the joint Russian-Indian BrahMos Aerospace company. Hence, statement 2 is not correct.
