How is a NAVTEX receiver programmed to reject certain messages?

Correct Answer: Option B — By choosing a message category's single letter (A-Z) identifier and then deselecting or deactivating.

NAVTEX receivers allow operators to filter incoming messages by selecting or deselecting specific message category identifiers (A-Z). Each letter corresponds to a type of information, such as weather or navigational warnings. This feature prevents the printer from being overwhelmed by irrelevant or non-essential data for the vessel's voyage.
