Answer:
d. malleus > incus > stapes > oval window
Explanation:
Sound waves enter external auditory canal which makes the eardrum to vibrate. Malleus is in contact with eardrum while stapes is in contact with the oval window. Movement of malleus makes the incus to move which in turn stimulates large movement in stapes.
Since stapes is in contact with the oval window, the vibration from stapes passes to the oval window. Hence, among the given options, the correct order of movement of sound waves is "malleus > incus > stapes > oval window"
