The correct answer is (a) RF environment awareness

For explanation: RF awareness means to be aware of spectrum utilization, spectrum users, topology, interference, and other RF characteristics. Radio transceiver database, cooperative sharing, sensor networks, and field measurement are the methods applied to gain RF environment awareness.
