If your vessel is in the POR, which of the following is a correctly formatted Inmarsat-C address book entry for sending communications to a shoreside TELEX terminal number 42267 in Ecuador (TELEX country code 308)?

Correct Answer: Option A — 30842267

Inmarsat-C shore-to-ship or ship-to-shore Telex addressing requires the country code followed by the subscriber number. For Ecuador (308) and terminal 42267, the concatenated string 30842267 is the standard format. No special characters or prefixes are required for standard Telex routing within the Inmarsat-C network architecture.
