You are standing radio watch and monitoring VHF Channel 16 when you receive a call to your rig, TEXAS STAR, from a supply boat. What is the proper way to answer this call?

Correct Answer: Option D — 'This is TEXAS STAR, WSR 1234, reply Channel 10.'

Marine radio protocol mandates that responding to a VHF radio call includes stating the vessel's name, call sign, and proposing a working channel to clear Channel 16 expeditiously, ensuring maritime safety frequencies remain open for emergency and calling traffic.
