WiMAX is related to which one of the following ?

WiMAX (Worldwide Interoperability for Microwave Access) is a wireless broadband communication standard designed to provide high-speed internet access over wide areas and is based on the IEEE 802.16 family of standards, often described as a metropolitan-area wireless broadband technology [1]. It was developed to deliver last‑mile broadband services as an alternative to wired technologies (DSL, cable) and to provide wide-area wireless broadband connectivity with significant range and throughput advantages over Wi‑Fi. Given these defining characteristics—standards-based wireless broadband access, IEEE 802.16 linkage, and metropolitan/wide-area scope—WiMAX is clearly a communication technology.
