In the electrolysis of aqueous sodium chloride solution, which of the half cell reaction will occur at anode ?
A. `Cl_((aq))^(-)to(1)/(2)Cl_(2)+e^(-)," " E_(cell)^(@)=1.36" volts"`
B. `2H_(2)O_((l))to O_(2)+4H^(+)+4e^(-) , E_(cell)^(@)=1.23" volts"`
C. `Na_((aq))^(+)+e^(-) toNa_((s)) , " " E_(cell)^(@)=-2.71" volts"`
D. `H_((aq))^(+)+e^(-) to (1)/(2)H_(2) , " " E_(cell)^(@)=0.00" volts"`
