Why can't impedances in series in an AC circuit simply be added to find the total circuit impedance?
 
  A) Because the total impedance is always lower than the lowest single impedance in a series circuit
  B) Because the currents through inductive, capacitive, and resistance loads in an AC circuit are out of phase with each other.
  C) Because the impedance stays the same throughout a series circuit
  D) Because some of the impedance is lost through each load
