Our Ability to Distinguish One High-Frequency Sound from Another-For Example

Our ability to distinguish one high-frequency sound from another-for example, 8000 Hz from 9000 Hz-depends on

A) which part of the basilar membrane has hair cells with the greatest activity.
B) the frequency of action potentials produced by each axon in the auditory nerve.
C) differences in response between cells in the left ear and cells in the right ear.
D) differences in the velocity of individual action potentials of the auditory nerve.
