Answer
(a) Stapes.
The STAPES is the last of the three ear ossicles, and it fits into the OVAL WINDOW, passing the vibrations into the fluid of the inner ear.
The chain in order from the eardrum inwards: MALLEUS (hammer) → INCUS (anvil) → STAPES (stirrup). The question asks which one passes vibrations INTO the inner ear, so it must be the last in the chain.
Option (d) COCHLEA can be eliminated at once: it is not an ossicle at all but the coiled organ of the inner ear that receives the vibrations.
Why the ossicles exist: they AMPLIFY the vibrations, which is necessary because it takes much more force to set a liquid vibrating than air. The stapes is also the smallest bone in the human body.
