(D) external ear, external auditory canal, tympanic membrane, middle ear, inner ear

EXPLANATION:

The sound waves first enter the external ear and then through the auditory canal, it reaches the three small bones of the ear. During its journey between the auditory canal and bones, the sound waves cause the eardrum or tympanic membrane to vibrate. As it reaches the middle ear, it causes the three bones to vibrate. In return, the small hairs of cochlea vibrate in the inner ear.
