The Voltaic Cell Made Up of Cobalt, Copper, and Their

The voltaic cell made up of cobalt, copper, and their M²⁺ ions, has E°_cell = 0.62 V. If E° of the cathode half-cell is 0.34 V, what is E° of the anode half-cell? Cu²⁺(aq) + Co(s) → Cu(s) + Co²⁺(aq)

A) −0.28 V
B) −0.96 V
C) 0.28 V
D) 0.96 V
E) None of these choices are correct.
