Answer: c. The Gravitational Force forms an action-reaction pair
Step-by-step explanation:
Newton's third law of motion talks about how for every amount of force exerted, there is an equal yet opposite reaction force exerted. This gives rise to Action-Reaction pairs.
Gravitational force forms an action-reaction pair when it is exerted for instance, the Gravitational force exerted on a person by the Earth is a person's weight. At the same time however, the person is exerting a gravitational force on the earth in the form of their weight.
