Specification for a wireless LAN are called
A
Standard 802.3z
B
Standard 802.3u
C
Standard 802.3x
D
IEEE 802.11
Explanation: 

Detailed explanation-1: -IEEE has defined the specifications for a wireless LAN, called IEEE 802.11, which covers the physical and data link layers. o IEEE 802.11 defines the basic service set (BSS) as the building block of a wireless LAN.

Detailed explanation-2: -An IEEE 802.11 WLAN is intended to be used as a physical layer in conjunction with the IEEE 802.2 logical link control (LLC) protocol. Given that the MAC protocol is based on CSMA/CA (collision sense multiple access with collision avoidance), an IEEE 802.11 WLAN is, in effect, a ‘wireless ethernet’ (Figure A6. 1).

Detailed explanation-3: -IEEE 802.11a is an amendment to the 802.11 standard for wireless LANs. It is of of the specifications that is more commonly known as Wi-Fi.

Detailed explanation-4: -Wireless LANs are those Local Area Networks that use high frequency radio waves instead of cables for connecting the devices in LAN. Users connected by WLANs can move around within the area of network coverage. Most WLANs are based upon the standard IEEE 802.11 or WiFi.
