According to the third law of motion, action and reaction always act on different bodies in opposite directions (Option 4)

Explanation:
Newton’s third law of motion states that “For every action, there is an equal and opposite reaction.”

It means that whenever one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.

To understand this law, it’s important to remember that forces always come in pairs, known as action-reaction pairs. Each force in the pair acts on a different object, and their magnitudes are always equal and their directions are always opposite.

For example, if you push a box with a force of 10 Newtons to the right, the box will push back on you with a force of 10 Newtons to the left.
