What equipment can be used to receive Maritime Safety Information?

Correct Answer: Option D — All of the above

Maritime Safety Information (MSI) is disseminated via multiple GMDSS subsystems to ensure redundancy. NAVTEX provides localized information, EGC (Enhanced Group Call) via Inmarsat covers ocean regions, and HF NBDP provides long-range coverage. Vessels must be equipped to receive these broadcasts to maintain awareness of navigational and meteorological warnings.
