B
Correct answer
Explanation
Bluetooth is not a line-of-sight technology - it uses radio frequency waves that can penetrate walls and obstacles. LOS technologies like infrared require an unobstructed path, but Bluetooth can work through non-metallic barriers, though range and quality may be reduced.
AI explanation
Bluetooth uses radio-frequency (RF) signals in the ISM band, which can pass through walls and obstacles and doesn't require the transmitter and receiver to be pointed at each other. That's what distinguishes it from truly line-of-sight technologies like infrared (IrDA), which do require an unobstructed direct path.
