Your ship received a Distress relay on DSC VHF channel 70, on what channel would you reply?

Correct Answer: Option D — Ch-16

VHF Channel 16 is the designated international distress, safety, and calling frequency for radiotelephony. When a DSC distress alert is received on Channel 70, the operator must immediately switch to Channel 16 to listen for follow-on voice communications from the distressed vessel or the rescue coordination center.
