What best defines a Wide Area Network (WAN)?

A Wide Area Network is defined by its reach: it connects networks over large geographic distances, tying together multiple sites with services from a telecom carrier or Internet service provider. This broad scope allows offices, data centers, and remote locations to share resources as if they were on a single network, typically using VPNs, MPLS, or dedicated leased lines over public or private infrastructure. The other options describe networks limited to a single building, or local wireless setups, or peer-to-peer file sharing—none of which capture the idea of interconnecting dispersed sites across wide areas.
