Which code matches the description 'Reverse switch correspondence relay'?

Explanation:
Conceptually, these three-letter codes identify a device by its type, its related function group, and its specific function. Here, the first letter signals a relay. The sequence “RW” captures the reverse switch aspect. The last letter tells the exact function, and “C” stands for correspondence. Put together, a relay whose role is reverse switch correspondence is encoded as RWC. The other options change the final function letter or the middle letters, so they don’t denote correspondence for a reverse switch.
