The correct answer is B.

OBJ-1.2: A personal area network (PAN) is centered around a short distance, usually around a person or up to a few meters. PANs are heavily used with Bluetooth and NFC. A local area network (LAN) connects computers within a small and specific area geographically. A metropolitan area network (MAN) is confined to a specific town, city, or region. It covers a larger area than a LAN but a smaller area than a WAN. A wide area network (WAN) will typically cover a larger area geographically, such as a continent, a state, or a country.
