Which of the following is a correct dialing sequence for a vessel in the western Atlantic to send a FAX to a U.S. destination using an Inmarsat-B terminal?

Correct Answer: Option C — 001# 0015036943254#

For Inmarsat-B facsimile transmissions via Southbury (001), the sequence requires the access code 001#, followed by the international prefix 00, the US country code 1, and the full subscriber number. The # key acts as the mandatory terminator to signal the completion of the dialing string to the station.
