Spring & Elastic Energy

The restoring force of a spring with a block attached to the free end of the spring is represented by

Show answer and solution

Answer: (a)

Restoring force obeys Hooke's law: $F_x = -kx$ .
This is a straight line through the origin with negative slope ( $F_x < 0$ for $x > 0$ , $F_x > 0$ for $x < 0$ ).
So the answer is (a).
