Question 305 Deck Safety

The correct answer is B) RQ. The RQ signal, when flashed with a light, changes a statement into a question. This is in accordance with the International Code of Signals, which is the standard used for maritime communication, including signaling by flashing light. The other options are incorrect because: A) N is the signal for "No" or "Negative." C) C is the signal for "Affirmative" or "Yes." D) NO is the literal word for negation, not a signaling code.
