If a GMDSS Radio Operator initiates a DSC Distress transmission but does not insert a message, what happens?

Correct Answer: Option C — The transmission will be made with "default" information provided automatically.

DSC equipment is programmed to transmit a 'default' distress alert if the operator fails to input specific details. This ensures that even if an operator only presses the distress button, the alert still contains the vessel's MMSI and position, preventing the loss of critical time during emergencies.
