If your vessel is in the AOR-E, which of the following is a correctly formatted Inmarsat-C address book entry for sending communications to a shoreside TELEX terminal number 776424 in Canada via the TWX system (TELEX country code 26)?

Correct Answer: Option B — 26776424

Telex addressing for the TWX system follows the same logic as standard Telex: country code followed by the subscriber number. With country code 26 and terminal 776424, the entry is 26776424. Ocean region prefixes are not included in the address book entry itself, as the LES handles routing.
