Why each option
IEEE 802.11b is the standard that defines wireless LAN (WLAN) communication operating in the 2.4 GHz band.
IEEE 802.4 defines the Token Bus standard used in industrial control networks, not wireless LANs.
IEEE 802.3 defines wired Ethernet (CSMA/CD) over copper and fiber, not wireless networking.
IEEE 802.11b is part of the 802.11 family specifically designed for wireless local area networks, operating at 2.4 GHz with a maximum data rate of 11 Mbps. It defined early WLAN interoperability and is the direct answer to which standard governs WLANs among the choices provided.
IEEE 802.5 defines the Token Ring standard for wired LANs using a token-passing access method, not wireless.
