Answer A is nonsense. 802.1x can authenticate both users and clients. Answer B is even more nonsense as it says that 802.1x never uses encryption which it always does. Answer C is correct. 802.1x always uses EAP (authenticating either a user or client, can be either one of them). EAP is a layer 2 protocol.

Answer is B: In case of 802.1X Authentication , Client is authenticated before getting IP address. In case of Captive Portal Authentication , Client is authenticated after getting IP address so that he can access the web Page (Captive Web Portal) for authenticating
