Show answer & explanation
Correct answer: B
IEEE 802.11 wireless LAN standards utilize CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) as their media access control protocol. This mechanism helps devices avoid data collisions when transmitting over the shared wireless medium, distinguishing it from protocols like CSMA/CD used in wired Ethernet.
