Which of the following net cell reactions occurs in a galvanic cell containing cadmium electrode and standard hydrogen electrode?
$\text{E}^\circ_{(\text{Cd}^{2+}_{(aq)}|\text{Cd}_{(s)})} = -0.403\ \text{V}$.

$\text{H}_{2(g)} + \text{Cd}^{2+}_{(aq)} \longrightarrow 2\text{H}^+_{(aq)} + \text{Cd}_{(s)}$

$\text{Cd}_{(s)} + 2\text{H}^+_{(aq)} \longrightarrow \text{Cd}^{2+}_{(aq)} + \text{H}_{2(g)}$

$2\text{H}_{2(g)} + \text{Cd}^{2+}_{(aq)} \longrightarrow 4\text{H}^+_{(aq)} + \text{Cd}_{(s)}$

$2\text{Cd}_{(s)} + 2\text{H}^+_{(aq)} \longrightarrow 2\text{Cd}^{2+}_{(aq)} + \text{H}_{2(g)}$
