BX
CY
DZ
AI Explanation
The correct answer is B) X. The high pressure cutout is indicated by component X in the illustration GS-RA-12. This component is responsible for shutting off the engine or fuel supply when the system pressure exceeds a certain threshold, preventing damage to the engine or fuel system. This feature is a critical safety mechanism required by the US Coast Guard regulations for vessels operating under a Captain's License. The other lettered components, W, Y, and Z, likely represent other essential parts of the fuel or engine system, but they do not specifically indicate the high pressure cutout function.
