Question 316 Deck Safety

The correct answer is A) R750. The USCG Captain's License examinations test the candidate's knowledge of marine signaling and communications. In this case, the question is asking about the appropriate signal to send the group "Distance 750 nautical miles". The correct answer is A) R750, as this signal is used to indicate the distance in nautical miles. The "R" stands for "range" or "distance", and the following number "750" indicates the distance of 750 nautical miles. The other options are incorrect, as they do not follow the standard signaling format for indicating distance.
