Solution
The correct option is C tectorial membrane Tectorial membrane is a thin elastic membrane present above the rows of the hair cells of organ of corti. It is involved in the mechanism of hearing. Tympanic membrane, also called eardrum, is a thin layer of tissue that receives sound vibrations from the external ear and transmits these sound vibrations to the ear ossicles in the middle ear. Reissner’s membrane is another membrane present within cochlea which separates scala vestibuli and scala media. Basilar membrane is a membrane present within the cochlea of the inner ear which separates scala media from scala tympani.
