D Correct answer
Explanation

The force that causes a spring to return to its normal length is called the restoring force. Restoring force is the force that brings a spring back to its equilibrium position after being stretched or compressed. It follows Hooke's Law (F = -kx) where the force is directly proportional to displacement and acts in the opposite direction. Potential force is not a standard term, gravitational force acts on masses, and spring force is ambiguous.
