According to newton's third law of motion, if you push against a wall, the wall will
a. attract you with its low gravity
b. fall over once you overcome its inertia
c. push against you with equal force
d. heat up due to energy transfer

It would be C as the law says "Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object."
