Which code is for 'Reverse switch repeater relay'?

Explanation:
In railroad signaling code, letters in a three-letter code map to a specific piece of equipment and its function. The device described as a Reverse switch repeater relay is encoded with the code that directly matches that description. The combination that corresponds to “Reverse switch repeater relay” is RWP, so this is the best choice because it exactly aligns with the equipment name in the standard code set. The other codes refer to different equipment types or functions, so they don’t describe a reverse switch repeater relay.
