The given figure shows a capacitor C and a resistor R connected in series to an ac source. $V_1$ and $V_2$ are voltmeters and A is an ammeter. Which of the following statements is correct ? (a) Current in the circuit lags in phase with voltage shown in $V_2$. (b) The voltage shown in $V_1$ is ahead in phase with voltage shown in $V_2$. (c) The current in the circuit and the voltage shown in $V_1$ are always in phase. (d) The voltage shown in $V_1$ lags behind in phase with the voltage shown in $V_2$.
