D. friction.

Answer 1

"Gravity" is the force that causes you to stay in the chair without letting you fell.

Option: C

Explanation:

According to “Newton's third law”, "For Every action there is an equal and opposite reaction". Similarly, in this case, if I'm on a chair and the gravity is pulling me with a force of 9.8 N, and equal force in opposite direction is helping me to be sited in the chair. This is the reason that all the objects on this planet are on the surface yet the gravitational forces attract it. This is only possible because of Newton's third law.
