Given that $E^{\circ }\left({\mathrm{Zn}}^{2+}\mid \mathrm{Zn}\right)=-0.76\mathrm{V},E^{\circ }\left({\mathrm{Cd}}^{2+}\mid \mathrm{Cd}\right)=-0.40\mathrm{V}$  and $E^{\circ }\left({\mathrm{Co}}^{2+}\mid \mathrm{Co}\right)=1.82\mathrm{V}$ Which of the following order regarding the reducing power of metals is correct? 

More positive potential means more easily ion is reduced and more difficult is the oxidation of the corresponding atom and thus less is its reducing power.

The order regarding the reducing power of metals is correct as, $\mathrm{Co}<\mathrm{Cd}<Z\mathrm{n}$
