The underlying technology for wireless local area networks is based on which specification?

Explanation:
Wireless local area networks run on a family of standards known as IEEE 802.11. This specification defines how wireless devices communicate over air, covering both the physical layer (radio frequencies and modulation) and the data link layer (how devices share the medium and manage access), which is what enables Wi‑Fi networks. It also includes security and networking features that evolve with newer amendments (such as 802.11a/b/g/n/ac/ax). Other technologies listed—Bluetooth, USB, and NFC—serve different purposes: Bluetooth for short-range personal devices, USB for wired peripheral connections, and NFC for very close-range contactless communication. So the underlying technology for wireless LANs is IEEE 802.11.
