(A)    The gradual increased height of stereocilia is required for the transduction process.
(B)    The changes of membrane potential of auditory hair cells are proportional to the direction and magnitude of the displacement of stereocilia.
(C)    The higher concentration of K+ in endolymph and higher concentration of Na+ in perilymph are not required for the excitation of hair cells.
(D)    The mechanically sensitive cation channels on the top of stereocilia are not adapted to maintain displacement of stereocilia.
