Answer: C

Explanation: Very high frequency omnidirectional range is a radio navigation system incorporated in aircrafts to stay on route with the help of radio signals transmitted by a network of ground radio beacons. A prominent feature of VOR is that the bearing from the station to the aircraft is unaffected by wind and orientation of the aircraft.
