• A. VOR
• B. DME
• C. NAVAIDs
• D. ILS

Answer: (C)

When radio communications fail, you must make your intentions known by every available channel. The voice capability of navigational aids adds a broadcast option you can use to reach ATC and other pilots in the area, even if your own radio isn’t working. That means you can broadcast your clearance or position/intentions via the NAVAID’s voice channel. The other items are navigation aids themselves and don’t provide this voice-broadcast channel, so the navigational aids’ voice feature is the appropriate method to use in this situation.
