With Respect to Its Resonant Frequency (220 Hz), Why Would

With respect to its resonant frequency (220 Hz) , why would the lower frequency (70 Hz) result in greater hyperpolarization (more inhibition) of outer hair cells?

A) Inhibition of neighboring outer hair cells contributes to the increased inhibition.
B) Lower tones (frequencies) are more difficult to detect, requiring a greater difference in membrane potential.
C) At lower frequencies, electromotility is inhibited.
D) Elongated outer hair cells mean that the greater membrane surface area exposes more cholinergic receptors.
E) Inner hair cells are inhibited through increased potassium conductance, driven by the Nernst equilibrium potential for potassium.
