Strategy:
 Internal energy () is a state function. This means the change in internal energy () for any process depends only on the initial and final states, not on the path taken.

Step 1: Analyze cyclic processes
In all three cases, the system undergoes a complete cycle starting and ending at the same point (A). For any cyclic process, the net change in a state function is always zero.
