C Correct answer
Explanation

Wireless access points use CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) to handle multiple users and distributed access. Unlike CSMA/CD used in wired Ethernet, CSMA/CA avoids collisions through acknowledgments and random backoff timers, since wireless devices cannot detect collisions during transmission. Token passing is used in Token Ring networks. Polling is a controlled access method but not the standard for Wi-Fi. CSMA/CD cannot work in wireless because stations cannot detect collisions while transmitting.
