Use the Standard Half-Cell Potentials Listed Below to Calculate the Standard

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25 °C.(The equation is balanced.)
$\quad$$\quad$ Mg(s) + Cu²⁺(aq) → Cu(s) + Mg²⁺(aq)
Mg²⁺(aq) + 2 e^- → Mg(s) $\quad$$\quad$ E° = -2.38 V
Cu²⁺(aq) + 2 e^- → Cu(s) $\quad$$\quad$ E° = +0.34 V

A) +2.04 V
B) -2.04 V
C) +2.72 V
D) -1.36 V
