Pressure Waves Passing Through the Perilymph of the Cochlea Compress

Pressure waves passing through the perilymph of the cochlea compress the vestibular membrane, and ultimately displace the basilar membrane. What is true of these waves?

A) High frequency waves (high notes) depress the basilar membrane midway along its length.
B) High frequency waves (high notes) depress the basilar membrane closest to the distal end of the cochlea.
C) High frequency waves (high notes) depress the basilar membrane all along its length.
D) High frequency waves (high notes) depress the basilar membrane closest to the middle ear.
