Which action is the most appropriate action for a GMDSS radio Operator to take in a Distress situation where immediate help is needed, but the vessel is not sinking nor needs to be abandoned?

Correct Answer: Option B — Transmit Distress call by HF/MF/VHF DSC or Inmarsat.

When immediate assistance is required without abandoning ship, transmitting a distress call via VHF, MF, HF DSC, or Inmarsat ensures direct communication with Rescue Coordination Centers. This initiates professional SAR coordination while maintaining the vessel's stable platform.
