Given \[F{{e}^{3+}}(aq)+{{e}^{-}}\to F{{e}^{2+}}(aq);\]\[E{}^\circ =+0.77\,V\] \[A{{l}^{3+}}(aq)+3{{e}^{-}}\to Al(s);\]\[E{}^\circ =-1.66\,V\] \[B{{r}_{2}}(aq)+2{{e}^{-}}\to 2b{{r}^{-}};\,\,E{}^\circ =+1.09\,V\] Considering the electrode potentials, which of the following represents the correct order of reducing power?

A) \[F{{e}^{2+}}<Al<B{{r}^{-}}\]

B)        \[B{{r}^{-}}<F{{e}^{2+}}<Al\]

C) \[Al<B{{r}^{-}}<F{{e}^{2+}}\]

D)        \[Al<F{{e}^{2+}}<B{{r}^{-}}\]
