Solution

The correct option is B It converts ear drum vibrations into electrical impulses.
The cochlea is a snail shell-like structure present in the inner ear that converts the vibrations of the ear drum or the tympanic membrane into electrical impulses. These electrical signals are then transmitted to the brain via the auditory nerve which then will aid us in hearing.
