Local passive current flow decreases with distance because
 a. ion pumps which drive current flow run out of energy (ATP) as they drift from the stimulus site.
  b. current leakage across the membrane attenuates current available for intracellular current flow.
  c. as it gets away from the active zone, the membrane fluidity decreases and prevents influx of booster current.
  d. of all of these reasons.
  e. of none of these reasons.
