Answer 1

The correct option is C The three tiny bones in an ear act as a system of levers and sound vibrations pass through them to the brain.

The three tiny bones in the middle part of an ear act as a system of levers and sound vibrations pass through them on the cochlea, not the brain. Cochlea sets up the vibrations or electrical impulses that are received by the auditory nerve and sent to the brain.
