Pick out the correct statement

ANS:C - Rocket engines carry oxygen required for the combustion in the form of oxidiser.

The correct statement is: Rocket engines carry oxygen required for the combustion in the form of oxidiser. This statement is accurate. Rocket engines carry both fuel and oxidizer onboard, which are typically stored in separate tanks. The oxidizer provides the oxygen necessary for the combustion of the fuel in the engine's combustion chamber, allowing the rocket to operate even in environments where there is no external atmosphere. This is in contrast to jet engines, which rely on the intake of atmospheric air for combustion and therefore cannot function in environments where there is no atmosphere.
