Explanation
Class 3 Bluetooth devices have the shortest range of approximately 1 meter. These are low-power devices typically used for very short-range applications like personal area networks with minimal separation distance. Classes 1 and 2 have much longer ranges (100m and 10m respectively).
AI explanation
Bluetooth power classes map to defined nominal ranges: Class 1 (100 mW) ~100 m, Class 2 (2.5 mW) ~10 m, and Class 3 (1 mW / 0 dBm) ~1 m. The correct range for a Class 3 transceiver is about 1 meter. The previously-marked '10 meters' is the Class 2 value, so the correct option (1 meter) was missing and has been added; '10 meters' is now un-marked.
