Final answer:
Very loud, high-frequency sound.The correct answer is option B.
Step-by-step explanation:
The type of sound most likely to have produced the pattern of damage described would be very loud, high-frequency sound.
The basilar membrane in the inner ear is responsible for detecting different frequencies of sound. High frequency sounds selectively vibrate the basilar membrane near the entrance port.
Lower frequencies travel farther along the membrane before causing appreciable excitation of the membrane.
Therefore, a very loud, high-frequency sound would have the potential to damage the hair cells on the basilar membrane close to the stapes.The correct answer is option B.
