Answer (Detailed Solution Below)
Option 4: Neither 1 nor 2
Detailed Solution
Explanation:
- 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. So, statement 1 is not correct.
- The Agni-V is an Indian intercontinental ballistic missile (ICBM) with a range of over 5,000 km. BrahMos is a universal long-range supersonic cruise missile system that can be launched from land, sea and air. BRAHMOS has been jointly developed by DRDO, India, and NPOM, Russia. So, statement 2 is not correct.
Therefore, option (4) is the correct answer.
