Answer: (c).Separate the external ear from the middle ear Explanation:The function of the outer ear is to include the external auditory canal and separate the external ear from the middle ear. The external auditory canal is an S-shaped tube that extends from the visible auricle to the tympanic membrane or eardrum. The eardrum separates the external ear from the middle ear and vibrates as sound waves enter the ear. The auricle or pinna helps in the collection and localization of sound waves.
