If more than one life raft is manned after the vessel has sunk, __________.

Correct Answer: Option D — tie each of the rafts together and try to stay in a single group

Tying life rafts together is a standard survival procedure that keeps survivors in a single group. This increases the visual profile for search aircraft, facilitates the sharing of resources and equipment, and ensures that the group remains together, which significantly improves the overall probability of successful rescue.
