The correct option is B Statement 1 is false but statement 2 is true
The stapes is the third bone of the three ossicles in the middle ear. The stapes is a stirrup-shaped bone and the smallest in the human body. The hearing part of the inner ear is rolled up into a spiral called the cochlea, as it looks like a snail shell. The cochlea is filled with fluid and contains the organ of Corti, a structure that contains thousands of specialised sensory hair cells with projections called cilia. The vibrations transmitted from the middle ear cause tiny waves to form in the inner ear fluid, which make the cilia vibrate. The hair cells then convert these vibrations into nerve impulses, or signals, which are sent via the auditory nerve to the brain, where they are interpreted as sound.
