Using the data given below:
`E_(Cr_(2)O_(7)^(2-)|Cr^(3+))^(@)=1.33V E_(Cl_(2)|Cl^(-))^(@)=1.36V`
`E_(MnO_(4)^(-)|Mn^(2+))^(@)=1.51V E_(Cr^(3+)|Cr)=-0.74V`
In which option the order of reducing power is correct?
A. `Cr^(3+)ltCl^(-)ltMn^(2+)ltCr`
B. `Mn^(2+)ltCl^(-)ltCr^(3+)ltCr`
C. `Cr^(+3)ltCl^(-)ltCr_(2)O_(7)^(2-)ltMnO_(4)^(-)`
D. `Mn^(2+)ltCr^(3+)ltCl^(-)ltCr`
