B) transport of vesicles to the plasma membrane, but only with high-frequency stimulation (e.g., 20 Hz) .
C) exocytosis that is independent of the frequency of stimulation.
D) opening of calcium channels, but only with low frequency stimulation (e.g., 1 Hz) .
E) inactivation of calcium channels that is independent of the frequency of stimulation.
