Best answer
The correct option is (d) Application policies

Easy explanation: The various characteristics of the unused spectrum bands determined during spectrum sensing depend on the time-varying radio environment, operating frequency, bandwidth, and quality of service requirements of the cognitive radio user. Spectrum management is required to correctly associate a user to a compatible spectrum band among all available spectrum bands in xG networks.
