Transmission of a Distress alert by a station not in itself in Distress should occur:

Correct Answer: Option D — In some cases, all of the preceding situations may justify a Distress Alert relay.

Distress relays are justified when the vessel in distress cannot communicate, when the Master deems it necessary to alert authorities, or when a Coast Station requires additional assistance. These actions are governed by IMO procedures to ensure that search and rescue resources are effectively mobilized during emergencies.
