70% to pass

In a message sent by flashing light, what group of letters will direct the receiver of a message to repeat the transmission back to the sender?

A UD AA
B RPB
C REPEAT
D RPT
AI Explanation

The correct answer is D) RPT. The International Code of Signals states that the group of letters "RPT" will direct the receiver of a message transmitted by flashing light to repeat the transmission back to the sender. This is a standard procedure used to ensure the message is received accurately. The other answer choices are incorrect because they do not correspond to the established protocol for requesting a message repeat. UD AA, RPB, and REPEAT are not the standardized signals used for this purpose in maritime communications.
