Question 318 Deck Safety

The correct answer is C) G10934. The reasoning is that the signal group used to indicate longitude is the letter "G" followed by the degrees and minutes of longitude. In this case, the longitude is 109°34'W, so the correct signal group would be G10934. The other options are incorrect because: A) L10934 is not the proper signal group format for longitude. B) LO10934W is not the proper signal group format, as the "LO" prefix is not used for longitude. D) D0934 does not correctly represent the longitude of 109°34'W.
