Which of the following is a correctly formatted Inmarsat-C address book entry for sending communications to a shoreside terminal number 276992 in New Jersey via TRT (TELEX country code 238)?

Correct Answer: Option A — 238276992

Telex addressing via Inmarsat-C follows the international format of the country code concatenated with the subscriber number. For country code 238 and terminal 276992, the correct entry is 238276992. This format ensures the Land Earth Station (LES) correctly routes the data packet to the intended terrestrial Telex network.
