Which of the following statements is true about a galvanic cell consisting of $\text{Cu}$ and $\text{H}_2$ electrodes ? (A) Oxidation occurs at copper electrode (B) Reduction occurs at $\text{H}_2$ electrode (C) $\text{H}_2$ is cathode and $\text{Cu}$ is anode (D) $\text{H}_2$ is anode and $\text{Cu}$ is cathode [Given : $\text{E}^\circ_{\text{Cu}^{2+}/\text{Cu}} = + 0\cdot34\text{ V}$, $\text{E}^\circ_{\text{H}^+/\text{H}_2, \text{Pt}} = + 0\cdot00\text{ V}$]
