Question 515Navigation General

The correct answer is A) 156.80 MHz (VHF-FM Ch. 16). The Coast Guard broadcasts urgent marine storm warning messages on VHF-FM Channel 16, which has a frequency of 156.80 MHz. This is the international distress, safety, and calling frequency used by maritime vessels, and it is the primary frequency the Coast Guard uses to disseminate critical safety information to the boating public. The other answer choices are incorrect, as they do not correspond to the frequency used for these important Coast Guard broadcasts.
