(D) The human ear consists of three parts: the outer ear,the middle ear,and the inner ear.$1$. The inner ear contains a complex structure called the labyrinth,which includes the cochlea and the vestibular apparatus.$2$. The cochlea is the coiled portion of the inner ear responsible for hearing.$3$. Inside the cochlea,there is a fluid-filled space containing the organ of Corti.$4$. The organ of Corti contains hair cells (sense cells) that act as mechanoreceptors.$5$. When sound vibrations reach the fluid in the cochlea,they cause the basilar membrane to vibrate,which bends the hair cells against the tectorial membrane,generating nerve impulses that are transmitted to the brain via the auditory nerve.

During the hearing mechanism in humans,the sense cells which perceive the sound vibrations are present in:
