The statement that is not true about LAN (Local Area Network) is:
(d) LANs can share data across the world.
LANs are typically designed for a small geographical area, such as within a building or campus. They are not intended for sharing data across the world. LANs operate at higher speeds than WANs (Wide Area Networks), and they can be privately owned networks, but their scope is limited to a local area. For sharing data across the world, wider-reaching network technologies like the internet (which consists of WANs and the global network infrastructure) are used.
