Final answer:
A LAN cannot be used to connect computers in different cities; it is used for more localized networks such as homes, offices, or schools.
Step-by-step explanation:
A Local Area Network (LAN) could be used to connect all of the following except for computers in different cities. LANs are designed to operate within a limited area such as a home, school, or office building. They enable connected devices to share resources and communicate with each other efficiently but are not intended for connecting geographically dispersed locations, which typically requires a Wide Area Network (WAN) or the internet. Therefore, options such as connecting computers in a home network, computers in an office building, and computers in a school are all feasible uses of a LAN.
