Best answer
Right answer is (b) Turn on white noise

The explanation: Turning on white noise can reduce the harsh noise. Turn on white noise is a counterintuitive, adding more pleasant noise on top of other noise. For example, the drone of a fan can be a pleasant white noise if you have a quality fan.
