Maryam almuhammadi · Accepted Answer

Final Answer : C, Explanation :  The hammer, anvil, and stirrup are three small bones in the middle ear that connect the eardrum to the cochlea. These bones transmit the vibrations from the eardrum to the cochlea, which then transforms them into electrical signals that are sent to the brain. The piston-like movement of the stirrup bone, the smallest bone in the human body, is what transmits the vibrations.
