Answer 1

The correct path is: 
External ear, External auditory canal, tympanic membrane, middle ear,  inner ear. 
Sound waves are first collected by the external ear or pinna. Sound waves then move through the external auditory canal to the tympanic membrane or the eardrum. Waves then move to middle ear which consists of the three small ear bones. The last stop is the inner ear which consists of the cochlea and auditory nerve.
