Question 4 Deck Safety

The correct answer is B) Mayday. The international distress signal "Mayday" is the spoken emergency signal that should be used over a VHF radio when there is a life-threatening emergency or imminent danger to a vessel or person at sea. This is the standard emergency procedure specified in maritime regulations and protocols. The other options are incorrect - "Red Alert" is not a recognized distress signal, "Security" is used for urgent messages but not for true emergencies, and "Pan" is the signal for a less severe urgency condition, not a full distress situation.
