CSMA/CA stands for Carrier-sense multiple access/collision avoidance. It is a multiple access protocol used by IEEE 802.11 standard for wireless LAN. It's based on the principle of collision avoidance by using different algorithms to avoid collisions between channels.

CSMA/CD:- use IEEE 802.3  multiple access protocol lan.

option B
