Solution

The correct option is B Pinna - Auditory canal - Tympanic membrane - Malleus - Incus - Stapes - Cochlea - Auditory nerve
The outermost part of human ear is called pinna (external ear).
Pinna is followed by auditory canal. It is a tube by which pinna is connected to middle ear.
The auditory canal extends from pinna to tympanic membrane (ear drum).
Tympanic membrane is followed by three ear ossicles, malleus, incus and stapes.
Stapes is attached to oval window of cochlea and transfers the vibrations to the fluid of cochlea. Cochlea is a part of inner ear.
Inner ear contains vestibular apparatus and auditory nerve along with cochlea.
So, the correct answer is 'Pinna - Auditory canal - Tympanic membrane - Malleus - Incus - Stapes - Cochlea - Auditory nerve'.
