What mode allows the aircraft to receive bearing and station ID while ensuring radio silence?

The correct option is associated with the functionality of TACAN (Tactical Air Navigation) systems, which are designed to aid navigation for aircraft. When in TACAN receive mode, the system is able to pick up signals that provide bearing information and station identification without actively transmitting. This is essential for maintaining radio silence, as it allows an aircraft to determine its position and the location of navigation aids or other aircraft without broadcasting its own signals that might compromise its stealth or position.

In various operational contexts, particularly in military scenarios, maintaining radio silence can be critical for operational security and situational awareness. The receive mode enables this capability effectively. Other modes, while useful for different operational purposes, either require transmission or do not focus on the specific need for silence while receiving navigational data.
