Question

• D. Ear drum

Answer 1

The correct option is C

Cochlea

1. The cochlea is present in the inner ear.
2. There is perilymph in the cochlear region which circulates depending on the vibrations of the sound received by the eardrum.
3. The hair cells in the cochlea also vibrate with the circulating fluid.
4. The vibrations help to identify the quality of sound which is received.

Hence, the cochlea identifies the quality of sound in the human ear.
