Using the data given below
\[
\begin{array}{ll}
E_{\mathrm{Cr}_{2} \mathrm{O}_{7}^{2}}^{\ominus} / \mathrm{Cr}^{3+}=1.33 \mathrm{~V} & \mathrm{E}_{\mathrm{Cl}_{2} / \mathrm{Cl}}^{\ominus}=1.36 \mathrm{~V} \\
\mathrm{E}_{\mathrm{MnO}_{4}^{-} / \mathrm{Mn}^{2+}}^{\ominus}=1.51 \mathrm{~V} & \mathrm{E}_{\mathrm{Cr}^{3 *} / \mathrm{Cr}}^{\ominus}=-0.74 \mathrm{~V}
\end{array}
\]

find out in which option the order of reducing power is correct.
(i) \( \mathrm{Cr}^{3+}\mathrm{Cl}^{-}\mathrm{Mn}^{2+}\mathrm{Cr} \)
(ii) \( \mathrm{Mn}^{2+}\mathrm{Cl}^{*}\mathrm{Cr}^{3 *}\mathrm{Cr} \)
(iii) \( \mathrm{Cr}^{3+}\mathrm{Cl}^{-}\mathrm{Cr}_{2} \mathrm{O}_{7}^{2-}\mathrm{MnO}_{4}^{-} \)
(iv) \( \mathrm{Mn}^{2 *}\mathrm{Cr}^{3+}\mathrm{Cl}^{-}\mathrm{Cr} \)
