Standard reduction potential of the half cell reactions are given below `Co^(3+)(aq) + e^(1-) to Co^(2+)(aq) , E^0 = +1.81 V` `Au^(3+)(aq) + 3e^(1-) to Au(s) , E^0 = +1.40 V` `I_(2)(s) + 2e^(1-) to 2l^(1-)(aq) , E^0 = +0.54 V` `Cu^(2+)(aq) + 2e^(1-) to Cu(s) , E^0 = +0.34 V`

Options

A. `Au^(3+) and Cu`
B. `I_2 and Au`
C. `Co^(3+) and Cu`
D. `Co^(2+) and Cu^(2+)`
