Which address is correctly formatted for sending TELEX communications to a vessel in the POR?

The correct choice for sending TELEX communications to a vessel in the POR (Port Operating Region) is formatted as a specific and standardized code that reflects relevant numbers and characters used in maritime communication. The format typically involves the maritime country code followed by the vessel or unit's identification number.

In this instance, the first set of digits indicates the TELEX number assigned to a specific service or vessel. The option that ends without an additional character is aligned with standard conventions used in maritime communications.

In contrast, the other options that include the plus sign or have different starting numbers do not conform to the typical TELEX address structure required for vessel communications. The plus sign typically signifies additional information that is not a standard part of a basic TELEX number and therefore would not be appropriate for this kind of communication.

By selecting the first option, you are adhering to the correct formatting necessary for TELEX communications in the maritime context, ensuring that messages can be properly routed to the intended vessel.
