Answer:

D) The refrigerator did not move so no work was done.

Explanation:

The refrigerator did not move so no work was done. Jack did exert a force and he did have energy. His muscles were twitching and using stored chemical energy. No work is done, though, if the force or energy does not cause an object to move. No movement, no work.
