Explanation

802.1X is a port-based Network Access Control (NAC) standard created by the IEEE (Institute of Electrical and Electronics Engineers), making C correct. It uses EAP over LAN (EAPOL), which encapsulates EAP messages directly into Ethernet frames - no PPP is required - making B correct. A is wrong because 802.1X supports both wired and wireless LANs. D is wrong because EAP itself was defined by the IETF (RFC 3748), not 802.1X. E is wrong because PPP is not a requirement; EAPOL eliminates that dependency.
