In the context of auditory perception, which of the following statements is true?
 
  A) The frequency theory holds that the pitch of a sound is sensed according to the place along the basilar membrane that vibrates in response to it.
  B) The place theory notes that for us to perceive lower pitches, we need to match the frequency of the sound waves with our neural impulses.
  C) Neurons that carry auditory signals cannot fire more than 100 times per second due to the uneven lengths of the axons.
  D) The frequency theory appears to account only for pitch perception between 20 and a few hundred cycles per second.
