Solution
The correct option is D Gases ejected from behind
A jet plane ejects a jet of hot gases from its tail which rush downwards at a high speed and to conserve momentum, the rocket moves upwards.If it is considered to be flying horizontally much above the surface of earth, the jet of hot gases moves in one direction and the jet plane moves in forward direction. The jet of hot gases may be imagined to be moving due to the action force and the jet plane, therefore, moves due to the reaction force of the gases ejected from behind.
