Which of the Following Does Not Describe a Type of Neural

Which of the following does not describe a type of neural connection with hair cells?

A) IHC afferents, which convey messages from the hair cells to the brain, give rise to the perception of sound.
B) OHC afferents, which convey messages from the hair cells to the brain, convey information to the brain about the perception of sounds coming specifically from the basilar membrane.
C) IHC efferents, which lead from the brain to the hair cells, provide a way for the brain to control afferent responsiveness.
D) OHC efferents, which lead from the brain to the OHCs, transmit commands to the OHCs to change their length, thereby controlling the stiffness of regions of the basilar membrane.
