Question 321 Deck Safety

The correct answer is B) four or five numerals. The letter G when sent with a complement is typically used as part of a visual distress signal, such as the SOS signal. In this context, the letter G is often followed by four or five numerals, which represent the latitude and longitude of the vessel's position. This allows search and rescue teams to quickly locate the distressed vessel. The other options are incorrect because they do not align with the standard format for visual distress signals using the letter G. Two numerals or two letters would not provide the necessary location information, and three or four numerals would not be sufficient to accurately convey the vessel's latitude and longitude.
