What is the frequency range of Bluetooth?

1kHz to 1GHz
2.4 to 2.48GHz
3kHz to 300GHz
1.8 to 1.9GHz

The correct answer is: 2.4 to 2.48GHz

Bluetooth operates in the frequency range of 2.4 to 2.48GHz. Option A (1kHz to 1GHz) is too low of a frequency range, as Bluetooth is designed for short-range communication. Option C (3kHz to 300GHz) is too high of a frequency range, as it overlaps with other technologies such as Wi-Fi and cellphones. Option D (1.8 to 1.9GHz) is also too low of a frequency range. Bluetooth also operates in the 2.4GHz band because it is an unlicensed and widely available frequency band, allowing for global compatibility.
