In the electrolysis of aqueous sodium chloride solution, Which of the half cell reaction will occur at anode ?

$2{\mathrm{H}}_2{\mathrm{O}}_{\left(\mathrm{l}\right)}\to {\mathrm{O}}_2+4{\mathrm{H}}^{+}+4{\mathrm{e}}^{-}; {\mathrm{E}}_{\mathrm{cell}}^{°}=+1.23 \mathrm{volts}$

$2{\mathrm{H}}_{\left(\mathrm{aq}\right)}^{+}+{\mathrm{e}}^{-}\to \frac{1}{2}{\mathrm{H}}_2; {\mathrm{E}}_{\mathrm{cell}}^{°}=+0.00 \mathrm{volts}$

${\mathrm{Na}}_{\left(\mathrm{aq}\right)}^{+}+{\mathrm{e}}^{-}\to {\mathrm{Na}}_{\left(\mathrm{s}\right)}; {\mathrm{E}}_{\mathrm{cell}}^{°}=-2.71 \mathrm{volts}$

${\mathrm{Cl}}_{\left(\mathrm{aq}\right)}^{-}\to \frac{1}{2}{\mathrm{Cl}}_2+{\mathrm{e}}^{-}; {\mathrm{E}}_{\mathrm{cell}}^{°}=1.36 \mathrm{volts}$
