(C) rocket operates based on Newton's $3^{rd}$ law of motion and the principle of conservation of linear momentum.As the fuel burns,the rocket expels hot gases at high velocity in the downward direction.According to the law of conservation of momentum,the total momentum of the system (rocket + gases) remains constant in the absence of external forces.Since the gases gain momentum in the downward direction,the rocket gains an equal and opposite momentum in the upward direction,which provides the necessary thrust for the rocket to lift off.
