Bluetooth is designed for short-range communication.

• A. False
• B. It depends on the version
• C. Bluetooth is designed for short-range communication
• D. Bluetooth can operate at long range

Answer: (C)

Bluetooth is built to support wireless links between nearby devices, aiming to replace short cables with a simple, low-power connection in close proximity. In everyday use, most Bluetooth devices operate within about 10 meters, which covers typical room-to-room handoffs and quick device pairings. Some devices offer longer reach—class 1 devices can reach up to around 100 meters in optimal conditions, and newer Bluetooth specifications can extend range further in some modes—but these are exceptions driven by power and hardware, not the core purpose. The key idea is that Bluetooth targets short-range, convenient connections, which is why the statement is the best fit. While range can vary by hardware and version, the design intent remains to enable close-range wireless communication rather than long-range links.
