Newton's Third Law of Motion specifically states that for every action, there is an equal and opposite reaction. This principle emphasizes that forces always occur in pairs; when one object exerts a force on another, the second object exerts a force of equal magnitude in the opposite direction on the first object. This relationship illustrates the concept of mutual interaction between objects.

In this context, the action refers to the force exerted by one object, and the reaction is the force that the second object applies back. This foundational principle is pivotal in understanding motion and forces in physics and highlights how entities interact in a balanced way.

The other options point to different concepts in physics, which do not encapsulate the essence of Newton’s Third Law. For example, the relationship in mass and acceleration pertains to Newton's Second Law, gravity and weight discusses how gravitational pull affects mass, and force and resistance describe dynamics in contexts like friction or drag, not the equal and opposite interactions emphasized by the third law.
