The cochlea is the snail-shaped organ in the inner ear that contains fluid and hair cells which change sound waves into a neural signal. The ossicles (A) are the three tiny bones in the middle ear that transmit vibrations from the eardrum to the inner ear, while the pinna (B) is the visible outer part of the ear that helps collect sound waves. The outer ear (D) consists of the pinna and the ear canal leading up to the eardrum. Therefore, the best choice for the given description is C) cochlea.
