The correct option is
B Very loud
A loud, unwanted or unpleasant sound that causes discomfort is called noise. Noise levels can range from 0 to more than 120 dB. The intensity of the sound of normal conversation ranges between 35 to 60 dB. Prolonged exposure to very loud noise of 70 to 90 dB may lead to impairment of hearing. Noise beyond 140 dB becomes painful.
