Best answer
Correct choice is (d) With supplied power

The best explanation: A propeller creates a thrust force out of the supplied power. The magnitude of this force is not for a given propeller but depends on the velocity of the incoming air and the rotational velocity of the propeller and helps the propeller to create the forward thrust.
