ANSWER:
B. Increases
STEP-BY-STEP EXPLANATION:
We have that when a spring is stretched or compressed, it works against the restoring force of the spring. This work is stored as elastic potential energy in the spring. The more you stretch or compress the spring, the more work you do and the more energy you store.
The elastic potential energy therefore will depend directly on the length of elongation, the greater the length, the greater the potential energy.
With the above, we can conclude that the correct answer is B. Increases
