A block that slides on a rough surface slows down and eventually stops.The reverse process never occurs.That is,a block at rest never begins to move and accelerate on a rough surface without the action of an external agent.The second situation is forbidden because it would violate

The second law of thermodynamics states that in any spontaneous process, the total entropy of a closed system always increases over time. In this case, the block at rest on a rough surface cannot spontaneously start moving and accelerating without the action of an external agent because it would result in a decrease in entropy. Therefore, the reverse process is forbidden according to the second law of thermodynamics. None of the other choices (A, B, C, and E) address the specific violation in this scenario.
