Answer:

The Moon Pulls on Earth, and Earth pulls back on the moon.

Explanation:

Newton's third law of motion describes action and reaction forces. It tells that an object applies an action force on another and another object also exerts a reaction force on the first object. Both the action and reaction forces are of equal magnitude but they act in opposite direction.

Option (A) is an example of action- reaction pair i.e. "The Moon Pulls on Earth, and Earth pulls back on the moon". Earth exerts a gravitational force on the Moon. The gravitational pull of the Earth on the Moon is much more stronger than the pull of Moon on the Earth.

So, the correct option is (A).
