The correct answer is D. Implement cognitive radios in the physical layer. Cognitive radios can sense the environment, sense other RF devices' signals, and use different frequencies in response to the sensing results. This makes the device very flexible in terms of being able to adjust to different environments and also to be able to detect and evade…

Explanation
Cognitive radios can sense the environment, sense other RF devices' signals, and use different frequencies in response to the sensing results. This makes the device very flexible in terms of being able to adjust to different environments and also to be able to detect and evade jamming or scrambling attacks. By deploying cognitive radios, Mike can mitigate the effects of DoS/DDoS attacks that use jamming or scrambling techniques.
