Which of the following is/are correct process for the separation of given ions?
(a) \( \mathrm{Cu}^{2+} \) from the mixture of \( \mathrm{Cu}^{2+} \) and \( \mathrm{Cd}^{2+} \) in aqueous solution, filtrate
(b) \( \mathrm{Cu}^{2+} \) from the mixture of \( \mathrm{Cu}^{2+} \) and \( \mathrm{Cd}^{2+} \) in aqueous solution, \( \mathrm{Cu}^{2+}+\mathrm{Cd}^{2+} \stackrel{\text { Add excess }}{\mathrm{KCN}} \stackrel{\text { Pass } \mathrm{H}_{2} \mathrm{~S}}{\underset{\text { and filter }}{\longrightarrow}} \mathrm{Cu}^{2+} \) in the precipitate
(c) \( \mathrm{Zn}^{2+} \) from the mixture of \( \mathrm{Zn}^{2+} \) and \( \mathrm{Cu}^{2+} \) in aqueous solution, \( \mathrm{Zn}^{2+}+\mathrm{Cu}^{2+} \stackrel{\mathrm{H}_{2} \mathrm{~S}+\text { dil HCl }}{\longrightarrow} \stackrel{\text { Filter }}{\longrightarrow} \mathrm{Zn}^{2+} \) in the precipitate
(d) \( \mathrm{Fe}^{3+} \) from the mixture of \( \mathrm{Fe}^{2+} \) and \( \mathrm{Fe}^{3+} \) in aqueous solution, \( \mathrm{Fe}^{2+}+\mathrm{Fe}^{3+} \stackrel{\mathrm{NH}_{4} \mathrm{Cl}+\mathrm{NH}_{3} \text { solution and filter }}{\longrightarrow} \mathrm{Fe}^{3+} \) in the precipitate
