FEC SITOR transmissions might be used to?

Correct Answer: Option D — Either b) or c) might be possible

Forward Error Correction (FEC) SITOR is a broadcast mode used for Maritime Safety Information (MSI). Under IMO GMDSS standards, it facilitates one-way dissemination of weather, traffic lists, and NAVTEX data. Because FEC supports both broadcast MSI and specific TELEX-based distress communications, both options B and C are operationally valid applications.
