Aboard ship, SafetyNETTM messages can be received by which equipment?

Correct Answer: Option C — Dedicated receiver or optional receiver integrated in vessel's SES.

SafetyNET messages are received via an Enhanced Group Call (EGC) receiver. This functionality is typically integrated into the ship's Inmarsat-C Ship Earth Station (SES) or provided as a dedicated EGC receiver, allowing the vessel to receive MSI broadcasts regardless of their location within the Inmarsat satellite coverage area.
