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