Why each option
IrDA (Infrared Data Association) is a short-range, line-of-sight wireless technology used in Personal Area Networks (PANs) to connect nearby personal devices.
A MAN (Metropolitan Area Network) spans a city or campus and uses technologies like fiber or microwave, not short-range infrared.
A WAN (Wide Area Network) covers large geographic distances and relies on technologies such as leased lines or satellite, not IrDA.
A PAN is designed for very short-range communication between personal devices such as laptops, phones, and PDAs. IrDA uses infrared light for close-proximity, point-to-point data transfer, which fits precisely within the PAN scope of a few meters.
A LAN (Local Area Network) covers a building or floor and uses Ethernet or Wi-Fi, not infrared IrDA communication.
