What means are used to prevent the reception of unwanted broadcasts by vessels utilizing the NAVTEX system?

Correct Answer: Option B — Programming the receiver to reject unwanted broadcasts.

To manage the high volume of MSI, operators use the receiver's programming interface to reject unwanted broadcasts. By filtering out specific station IDs or non-essential message categories, the vessel ensures that only pertinent safety information is printed or displayed, reducing clutter and improving situational awareness on the bridge.
