D Correct answer
Explanation

Prolonged exposure to sounds at or above 120 dB can cause permanent hearing damage and deafness. This level of intensity is comparable to a jet engine at close range. Sounds at 85 dB can cause damage with long-term exposure, but 120 dB is the threshold where immediate damage becomes significant.
