Correct Answer: Option C
Explanation

The cochlea is a spiral-shaped structure in the inner ear that is filled with fluid and lined with cells with very fine hairs. These hairs move when the fluid in the cochlea moves, thereby converting sound vibrations into nerve signals that the brain can interpret. Therefore, the correct answer is 'Cochlea.' The eardrum and ossicles help to transmit sound vibrations to the cochlea, but it is the cochlea that transmits these vibrations as signals to the auditory nerve.

There is an explanation video available below.
