Of the force exerted on the rocket by gases ejected by it

(D) In accordance with Newton's $3^{rd}$ Law of Motion,the exhaust gases ejected from the rocket exert an equal and opposite force on the rocket,known as thrust.This thrust propels the rocket upward,enabling it to overcome the gravitational force of the Earth.Therefore,the correct reason for the rocket's upward motion is the force exerted on the rocket by the gases ejected by it.
