Answer : 3. "Inertia"
Explanation :

Answer: C) Inertia Explanation: To rotate is to energy to stop is to inertia. From the definition itself we know that inertia is a property by virtue of which a body continues to be in the state of rest or in state of motion. So over here whenever energy is supplied then the body starts to move that is a displacement is there and it is rotating where as whenever the body is stopped an inertia of rest is created.   So, Rotate : Energy :: Stop : Inertia.
