Based on the Information in the Table of Standard Reduction

Based on the information in the table of standard reduction potentials below, what is the standard cell potential for an electrochemical cell that has iron, Fe, and magnesium, Mg, electrodes? Also, identify the cathode.

A) (+3.14 V with Fe as the cathode)
B) (+3.14 V with Mg as the cathode)
C) (-3.14 V with Fe as the cathode)
D) (-3.14 V with Mg as the cathode)
E) (+1.60 V with Fe as the cathode)
