Which statement is false regarding the GMDSS requirement for ship sources of energy?

Correct Answer: Option B — The reserve sources of energy need to supply independent MF and HF radio installations at the same time.

IMO SOLAS regulations require the reserve source of energy to be capable of powering radio installations, but it is not required to power independent MF and HF installations simultaneously. The system must provide sufficient capacity to operate the required equipment for the specified duration during a total power failure.
