• Option B: Modems are used to connect LANs to the internet. Modems convert digital signals from computers into analog signals that can be transmitted over telephone lines. Once a modem is connected to a LAN, it allows users to access the internet.
• Option C: Printers are not essential for LANs, but they can be connected to a LAN to allow multiple users to print documents.
