Correct option (d) Satellite does not require any energy for orbiting.

Explanation:

A satellite rotates around the earth by using earth's gravitational force as centripetal force. Also as there is no air in space, it does not have to work against air resistance. Hence it doesn't lose any energy while rotating. So it does not require fuel/energ to rotate around the earth.
