    The refrigerator did not move so no work was done.

    Explanation:

    Work is defined as a product of force and distance. Jack exerted some force on the refrigerator hence it implies he had some energy. However, since the object didn't move, there was no work hence it's proper to conclude that The refrigerator did not move so no work was done. Therefore, option D is correct.
