Some half-cell reactions and their standard potentials are given as below:

\[MnO_{4}^{-}(aq)+8{{H}^{+}}(aq)+5{{e}^{-}}\xrightarrow{\,}\,M{{n}^{2+}}(aq)+4{{H}_{2}}O(l);\]\[{{E}^{o}}=1.51\,\,V\]

\[C{{r}_{2}}O_{7}^{2-}(aq)+14{{H}^{+}}(aq)+6{{e}^{-}}\to 2C{{r}^{3+}}(aq)+7{{H}_{2}}O(l);\] \[{{E}^{o}}=1.38\,\,V\]

\[F{{e}^{3+}}(aq)+{{e}^{-}}\xrightarrow{\,}\,F{{e}^{2+}}(aq);\]\[{{E}^{o}}=0.77\,\,V\]

\[C{{l}_{2}}(g)+2{{e}^{-}}\xrightarrow{\,}\,2C{{l}^{-}}(aq);\]\[{{E}^{o}}=1.40\,\,V\]

Identify the incorrect statement.

A)  \[MnO_{4}^{-}\]is weaker oxidizing agent than \[C{{l}_{2}}\]  

B)  \[C{{r}_{2}}O_{7}^{2-}\] is weaker oxidizing agent than \[C{{l}_{2}}\]

C)  \[MnO_{4}^{-}\]is stronger oxidizing agent than \[F{{e}^{3+}}\]

D)  \[C{{r}_{2}}O_{7}^{2-}\]is weaker oxidizing agent than \[MnO_{4}^{-}\]
