Why each option
IEEE 802.11b is the standard that defines wireless LAN (Wi-Fi) communications, making it the correct answer among the listed IEEE standards.
The IEEE 802.11 family of standards defines the protocols for wireless local area network (WLAN) communications, and 802.11b was one of the first widely adopted amendments specifying 2.4 GHz operation at up to 11 Mbps. All Wi-Fi networking is governed by this family, while the other listed standards cover entirely different network types.
IEEE 802.5 defines the Token Ring LAN standard, which is a wired technology using a token-passing access method on ring topologies - not wireless networking.
IEEE 802.3 defines Ethernet, the wired LAN standard using CSMA/CD over twisted-pair or fiber cabling - it has no wireless component.
IEEE 802.4 defines the Token Bus standard for wired industrial/manufacturing networks and is unrelated to wireless LAN technology.
