A Correct answer
Explanation

Bluetooth operates in the 2.4-2.48 GHz ISM (Industrial, Scientific, Medical) band. 2.45 GHz is the center frequency commonly cited. Options in MHz (megahertz) would be 1000x too small. BHz is not a standard unit. Hz alone is far too low. This is the same band used by WiFi and microwaves.
