Answer

Brief Explanations:

In physics, work is done when a force causes an object to move in the direction of the force. When Tina pulls the puppy toward her, she applies a force and causes a displacement in the direction of the force. In the other cases, there is no displacement in the direction of the applied force (holding steady has no displacement, and letting - go means she is no longer applying a force while the displacement occurs).

Answer:

whenever she pulls the puppy toward her
