Solution

The correct option is A A - Temporal bone, B - Malleus, C - Incus, D - Stapes, E - Cochlea, F - Eustachian tube, G - Tympanic membrane, H - External auditory canal
Temporal Bone contains the middle and inner portion of the ear and the lower part of it articulates with the mandible forming the temporomandibular joint of jaw.
There are three ear bones namely the malleus, the incus and the stapes, together they form a short chain that crosses the middle ear and transmit vibrations caused by the sound waves from the eardrum membrane to the inner ear.
The cochlea contains the spiral bone of Corti which is the receptor organ for hearing.
The eustachian tube maintains the air containing space to equalize the intratympanic air pressure with the pressure in the external auditory canal.
The function of the ear cannel is to transmit sound from the pinna to the eardrum.
So, option A is the correct option.
