The most likely location for a liquid cargo fire to occur on a tanker would be __________.

Correct Answer: Option D — in the pump room

The pump room is the most hazardous location on a tanker due to the concentration of cargo pumps, piping, valves, and seals. Mechanical failure, seal leaks, or bearing overheating can easily ignite flammable vapors, making it the most likely site for a liquid cargo fire during operations.
