For GMDSS, which statement concerning a compulsory vessel is FALSE?

Correct Answer: Option C — Once a compulsory vessel's GMDSS station has been fitted and inspected, the station must be inspected only once every five years.

GMDSS radio installations on compulsory SOLAS vessels must undergo statutory safety radio surveys and inspections annually, not every five years. The five-year claim is incorrect, making statement C the false requirement under international regulations.
