What system may be useful for messages, such as local storm warnings or a shore-to-ship Distress alert, for which it is inappropriate to alert all ships in the satellite coverage area?

Correct Answer: Option B — EGC

EGC allows for precise geographic addressing, enabling authorities to transmit local warnings or specific alerts to a defined area without alerting the entire satellite footprint. This prevents unnecessary distraction for vessels outside the affected zone, which is a critical operational advantage over broad-area broadcast systems like standard DSC.
