💡 A. Wide Area Network (WAN): This is the best option because a WAN connects multiple locations across different cities and countries. It allows organizations with global or multi-city operations to share data and resources over a large geographical area using telecommunications networks, satellite links, or the internet. B. Local Area Network (LAN): A LAN is designed for smaller, localized environments like offices, schools, or campuses. It would not be suitable for an organization operating in multiple cities or countries. C. Metropolitan Area Network (MAN): A MAN covers a larger area than a LAN but is limited to a single city or metropolitan region. It is not ideal for a globally or nationally distributed organization. D. Storage Area Network (SAN): A SAN is used specifically for data storage and retrieval, not for connecting multiple geographic locations. It supports high-speed access to storage devices but does not serve as a communication network between multiple cities or countries.
