Network covering a small local areaNetwork spanning a broad geographic regionDevice that converts signals for communicationEvery option listed above

Explanation

A local area network (LAN) covers a limited area, such as a home or office. A wide area network (WAN) extends over a large geographical area and often uses telephone systems for communication. A modulator-demodulator (modem) is a device for signal conversion, not a type of network. Therefore, the correct answer is a wide area network.
