What is meant by the term "radio silence"?

Correct Answer: Option B — Stations not directly involved with the on-going Distress communications may not transmit on the distress frequency or channel

Radio silence is a mandatory operational restriction requiring all stations not involved in the distress incident to cease transmissions on the affected frequency. This ensures that the distress channel remains clear for the distressed vessel and the coordinating rescue authorities to communicate without interference from other traffic.
