What Statement Is NOT True About Standard Electrode Potentials

What statement is NOT true about standard electrode potentials?

A) E°_cell ^{is positive for spontaneous reactions.}
B) Electrons will flow from more negative electrode to more positive electrode.
C) The electrode potential of the standard hydrogen electrode is exactly zero.
D) E°_cell is the difference in voltage between the anode and the cathode.
E) The electrode in any half-cell with a greater tendency to undergo reduction is positively charged relative to the standard hydrogen electrode and therefore has a positive E°.
