A membrane that supports the Organ of Corti and hair cells in the cochlea.
A
oval window
B
tympanic membrane
C
Basilar Membrane
Explanation: 

Detailed explanation-1: -The hair cells within the organ of Corti have sterocilia that attach to the tectorial membrane. Shifts between the tectorial and basilar membranes move these sterocilia and activate or deactivate receptors on the hair cell surface.

Detailed explanation-2: -…the basilar membrane is the organ of Corti, which contains the hair cells that give rise to nerve signals in response to sound vibrations. The side of the triangle is formed by two tissues that line the bony wall of the cochlea: the stria vascularis, which lines the outer wall…

Detailed explanation-3: -a fibrous membrane within the cochlea that supports the organ of Corti. In response to sound, the basilar membrane vibrates; this leads to stimulation of the hair cells-the auditory receptors within the organ of Corti.

Detailed explanation-4: -The organ of Corti is named after Italian anatomist Alfonso Corti, who first described it in 1851. Viewed in cross section, the most striking feature of the organ of Corti is the arch, or tunnel, of Corti, formed by two rows of pillar cells, or rods. The pillar cells furnish the major support of this structure.

Detailed explanation-5: -The basilar membrane is a stiff structural element within the cochlea of the inner ear which separates two liquid-filled tubes that run along the coil of the cochlea, the scala media and the scala tympani.
