In a voltaic cell based on the Cu-Zn reaction

Zn(s) + Cu2+ (aq) --> Cu(s) + Zn2+ (aq)
there is exactly 1 mole of each reactant and product. A second cell based on the Cd-Cu cell reaction
Cd(s) + Cu2+ (aq) --> Cu(s) + Cd2+ (aq)
also has exaclty 1 mole of each reactnat and product. Which of the following statements about the two cells is true?

A) The quantities of electrical energy that they can produce are the same
B) The masses of their elctrodes are the same
C) The quantities of electrical charge that are they can produce are the same
D) Their cell potentials are the same
