(C) The root mean square voltage is given as $V_{rms} = 220 V$.The relationship between the peak voltage $(V_0)$ and the $RMS$ voltage $(V_{rms})$ is $V_0 = V_{rms} \times \sqrt{2}$.Substituting the values: $V_0 = 220 \times 1.414$.$V_0 = 311.08 V$.Rounding to the nearest integer,the peak voltage is $311 V$.Therefore,the correct option is $C$.
