Which code best matches the description 'Reverse switch correspondence diagram light relay'?

Explanation:
This tests how the diagram code is built from the description. The description highlights three elements you must encode: Reverse, switch-related diagram, and a light-relay diagram. The code that signals a reverse operation, the switch aspect, and the specific diagram type for a light relay is the one that uses those three corresponding markers in sequence. In this case, the final symbol indicates the light-relay diagram, so the code that ends with that marker best matches the description. The other options point to different diagram subtypes and don’t align with the "light relay" part, so they’re not appropriate.
