Best answer
The correct option is (a) QoS maintenance

Explanation: xG networks change constantly in the wireless spectrum in accordance with the available spectrum band. The available spectrum bands tend to vary with time. Thus QoS maintenance becomes difficult.  The radio should alter its position to meet the QoS requirements.
