Solution

The correct option is B
False

The cochlea is filled with a watery liquid, the perilymph and endolymph which moves in response to the vibrations coming from the middle ear. As the fluid moves, the cochlear partition moves, thousands of hair cells sense the motion and convert that motion to electrical signals.
