Which statement best describes the function of a temperature relief device (TRD)?

Explanation:
A temperature relief device is a safety feature that prevents overpressure by venting the vessel when heat raises its internal temperature to a preset limit. It detects excessive heat on the vessel itself and automatically releases contents to quickly relieve pressure, preventing rupture or explosion. This is why it’s the best description: it focuses on automatic safety venting in response to high temperature, not on regulating engine temperature, measuring ambient air, or functioning as a manual valve.
