Arefrigerant receiver
Bhigh pressure cut-out

Dpressure relief device
AI Explanation
The correct answer is D) pressure relief device. According to 46 CFR Part 58, which covers marine engineering equipment and systems, all refrigeration systems are required to have a pressure relief device. This is to provide protection against excessive pressure buildup, which could be hazardous. The pressure relief device allows the system to safely release pressure if it exceeds a certain threshold, preventing potential damage or explosions. The other options, such as a refrigerant receiver, high pressure cut-out, or low pressure cut-out, may be important components of a refrigeration system, but they are not specifically required for protection purposes under the regulations outlined in 46 CFR Part 58.
