The correct answer is:
(c) Resolve conflicts
In the context of Cognitive Radio Architecture, prayer behavior refers to a decision-making or conflict resolution process. In cognitive radio systems, where multiple users and different spectrum access strategies may be involved, such behavior helps in managing and resolving conflicts that arise from the competing demands for spectrum resources.
The term "prayer behavior" isn't standard in cognitive radio, but it may refer to an algorithmic or heuristic method that ensures a conflict-free, efficient approach to resource allocation in a dynamic spectrum environment.
