Due in Part to the Physical Properties of the Basilar

Due in part to the physical properties of the basilar membrane, the cochlea is tuned so that

A) high amplitude sounds are perceived optimally at the base of the narrow end of the cochlea (toward the oval window) .
B) low amplitude sounds are perceived optimally at the base of the narrow end of the cochlea (toward the oval window) .
C) high frequency sounds are perceived optimally at the base of the narrow end of the cochlea (toward the oval window) .
D) low frequency sounds are perceived optimally at the base of the narrow end of the cochlea (toward the oval window) .
