The sound waves first enter the external ear, then travel through the auditory canal and cause the tympanic membrane (eardrum) to vibrate. This vibration is transmitted through the hammer, anvil, and stirrup (the three tiny bones of the middle ear) to the cochlea in the inner ear. Therefore, option C is the correct order.
