Solution

The correct option is D The Tympanic membrane
The tympanic membrane also called are drum is a thin membrane that receives sound vibrations or pressure and then change it into receptor potentials from the outer ear and transmits it to auditory or ear ossicles (tiny bone in tympanic ). The oval window is a membrane-covered opening that leads from middle to inner ear and Organ of Corti is the sensory organ for hearing and located in the cochlea.
So the correct option is "The Tympanic membrane'.
