The correct option is "Neither 1 nor 2" because both statements contain inaccuracies about missile classifications. Ballistic missiles are characterized by following a ballistic trajectory, typically launched at high speeds, and are primarily propelled by rockets after the initial boost phase; they do not maintain jet propulsion. Conversely, cruise missiles, which can be powered by jet engines throughout their flight, typically operate at subsonic or supersonic speeds. Additionally, Agni-V is an intercontinental ballistic missile (ICBM) with a long range, while BrahMos is a supersonic cruise missile, not a ballistic missile. Proper understanding of these classifications is essential for the UPSC syllabus, as it highlights the strategic and technological aspects of defense systems.
