A set of standards for wireless local area networks (WLANs).

• A. Bluetooth
• B. 802.11X
• C. NFC
• D. USB (A/B/C)

Answer: (B)

IEEE 802.11 defines the set of standards for wireless local area networks, the technology commonly called Wi‑Fi. This directly addresses how WLANs operate, including how devices connect, how data is transmitted, and how security and interoperability are handled. The other options correspond to different purposes: Bluetooth is for short-range personal area networks, NFC is for very close, quick exchanges, and USB is a wired interface. So the choice that points to the 802.11 family best matches the concept of standards for WLANs.
