Which code denotes the track relay?

Explanation:
In this signaling code, the track relay is denoted by the single letter T. The track relay is the device that monitors the track circuit and indicates whether the track block is occupied, which is essential for safe train movement. Among the options, T is specifically used for the track relay, making it the correct designation. The other codes (Sb, Tb, Te) represent different components in the system and are not used for the track relay, so they don’t fit as the track relay designation.
