None of above.

Detailed explanation-1: -His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions.
Detailed explanation-2: -Formally stated, Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
Detailed explanation-3: -Forces come in pairs. Newton’s 3rd Law says for every action, there is an equal and opposite reaction. An aircraft is a perfect real-world example of force pairs. Even sitting on the ground, the plane exerts a force down on the ground and the ground exerts an equal force back up on the plane.
Detailed explanation-4: -Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.
Detailed explanation-5: -Newton’s third law of motion states that for every action there is an equal and opposite reaction. These action-reaction forces act on two different bodies. E.g. while walking, we push the ground backward (action). The ground, in turn, pushes us forward (reaction) which helps us move on the ground.
