SOLAS requires which of the following with regard to watertight doors in cargo spaces?

Correct Answer: Option C — the operation of the door must be recorded

SOLAS Chapter II-1, Regulation 22 requires that the operation of watertight doors be recorded in the logbook. This ensures accountability for the integrity of the vessel's subdivision. While remote operation is often required for power-operated doors, the mandatory logging of door status is a fundamental safety requirement for all watertight closures.
