The only cations present in a slightly acidic solution are \( \mathrm{Fe}^{3+}, \mathrm{Zn}^{2+} \) and \( \mathrm{Cu}^{2+} \). The reagent that when added in excess to this solution would identify and separate \( \mathrm{Fe}^{3+} \) in one step is:
(a) \( 2 \mathrm{M} \mathrm{HCl} \)
(b) \( 6 \mathrm{MH}_{3} \)
(c) \( 6 M \mathrm{NaOH} \)
(d) \( \mathrm{H}_{2} \mathrm{~S} \) gas
