Question 308 Deck Safety

The correct answer is C) RPT. The groups "AA" and "AB" are used in conjunction with the group "RPT" in signaling by flashing light. This is in accordance with the International Code of Signals, which is the standard reference for signaling procedures used by the U.S. Coast Guard and other maritime authorities. The other answer choices are incorrect because they do not correspond to the groups used with "AA" and "AB" in flashing light signaling. "CS", "WA", and "RQ" are not the appropriate groups used in this context.
