The standard electrode potential ($E^{\circ }$) values of ${\text{Al}}^{3+}/\text{Al}$, ${\text{Ag}}^{+}/\text{Ag}$, ${\text{K}}^{+}/\text{K}$, and ${\text{Cr}}^{3+}/\text{Cr}$ are $-1.66\text{V}$, $0.80\text{V}$, $-2.93\text{V}$, and $-0.79\text{V}$ respectively. The correct decreasing order of the reducing power of the metal is:

1. A
   $\text{Ag}>\text{Cr}>\text{Al}>\text{K}$
2. B
   $\text{K}>\text{Al}>\text{Cr}>\text{Ag}$
3. C
   $\text{K}>\text{Al}>\text{Ag}>\text{Cr}$
4. D
   $\text{Al}>\text{K}>\text{Ag}>\text{Cr}$
