A Ramjet engine uses compressor and turbines and it works at subsonic speeds: This statement is incorrect. A Ramjet engine does not use compressors and turbines. Instead, it relies on the forward motion of the vehicle to compress incoming air. Ramjets operate at supersonic speeds, not subsonic.

A Scramjet operates at supersonic speed which uses the space craft’s forward motion to compress incoming air without an axial compressor: This statement is correct. A Scramjet (supersonic combustion ramjet) is a type of air-breathing jet engine that operates at hypersonic speeds. It relies on the forward motion of the vehicle to compress incoming air without the need for traditional compressors.

Therefore, the correct option is 2 only.
