Answer: C

Explanation: The DARPA NeXt Generation radio communication program aims to develop a radio with technology that can dynamically redistribute the available spectrum in radio networks, thereby making the best use of available communication bandwidth. The spectrum should be sensed automatically. The selected operating mode should maximize the survivability of communication networks and reduce the amount of interference to other users of the spectrum.
