Which of the following Multiple Access Protocols is not suitable for wired…

In Multiple Access Protocol, different protocols are used depending on whether the network is wired or wireless.

CSMA/CD (Collision Detection) → used in wired Ethernet networks

CSMA/CA (Collision Avoidance) → used in wireless networks (Wi-Fi)

Wired networks can detect collisions directly, but wireless networks cannot easily detect them, so they use avoidance instead.
