Cruise missiles are jet-propelled at subsonic, supersonic or hypersonic 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 incorrect.

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

A supersonic cruise missile 'BrahMos' is a joint venture between the Russian Federation's NPO Mashinostroyenia and DRDO. The name BrahMos is formed from the names of two rivers, the Brahmaputra of India and the Moskva of Russia.
