You are at sea in an inflatable life raft. In high latitudes, the greatest danger is __________.

Correct Answer: Option C — hypothermia caused by cold temperature

In high latitudes, the extreme ambient temperature and the conductive nature of the ocean make hypothermia the most immediate and lethal threat. Maintaining body heat is critical, as the raft provides limited insulation against the cold, necessitating strict adherence to survival procedures to prevent rapid core temperature loss.
