Which of the following is correctly formatted for sending TELEX to an Inmarsat-B terminal in the AOR-W?

The correct formatting for sending a TELEX to an Inmarsat-B terminal in the AOR-W is defined by the structure of the address used. In the case of Inmarsat-B, the address usually consists of a specific format that often includes a prefix that designates the service or operator, followed by the terminal number.

The address "584331014013" adheres to the established convention for TELEX formatting. It carries the correct prefix, which matches the requirements for routing messages to the Inmarsat-B service, ensuring that the TELEX is directed accurately to the intended recipient. This address does not require any additional characters or formatting elements that would complicate its transmission, thus maintaining compliance with the communication protocols.

In contrast, other options either do not align with the expected format for an Inmarsat-B TELEX or include extra characters that could potentially cause errors in routing the message. The inclusion of a '+' at the end of an address could indicate additional considerations or data that aren't typically part of standard routing for this service. As such, option B stands out as the correct choice for this specific communication format.
