When working with Newton’s Third Law, there has to be two objects involved.

Option D

Explanation:

Third law by Newton defines that the action and the reaction forces acting on different bodies. For any object under action, there will be an opposite force called reaction acting on the body.  Let us consider the movement of a car onto the home way.

A car seems to be well-equipped with wheels which rotate. While rotating or spinning, the wheel grips the road and instantly, the road is pushed backwards. Since force results due to mutual interactions, the road acts to push the wheels forward. Likewise, we have many examples like moving fish, motion of birds, etc.
