Question 159 Deck Safety

The correct answer is B) Safety message. The reasoning for this is that encountering an unreported iceberg poses a potential hazard to navigation, but does not necessarily represent an immediate threat or emergency situation. A safety message is used to convey important navigational or weather-related information that could affect the safety of a vessel or persons, but does not require immediate assistance. This allows other ships in the area to be alerted to the hazard and take appropriate precautions. The other options are incorrect because a routine message would not convey the urgency of the situation, a distress message is reserved for life-threatening emergencies, and an urgency message is used for situations that may affect the safety of a vessel or person, but do not require immediate assistance.
