What is meant by the term "radio silence"?

A Communications on a distress frequency or channel is banned for 24 hours following the cessation of the distress traffic
B Stations not directly involved with the on-going Distress communications may not transmit on the distress frequency or channel
C Two three-minute silent periods, at 15 and 45 minutes after the hour, that provide a transmitting "window" for distressed vessels to transmit distress alerts using J3E
D Stations remaining off the air to safeguard proprietary information
AI Explanation

The correct answer is B) Stations not directly involved with the on-going Distress communications may not transmit on the distress frequency or channel. "Radio silence" refers to a protocol where stations not directly involved in a distress situation are required to cease transmissions on the distress frequency or channel. This allows the stations handling the distress communication to coordinate the response without interference from other stations. The regulation ensures the distress frequency remains clear for the critical communications between the distressed vessel, rescue coordinators, and any vessels or aircraft involved in the rescue effort. The other options are incorrect because they do not accurately describe the meaning of "radio silence" in the context of maritime distress communications.
