Two resistors are arranged in series with a battery, as illustrated. The meter readings for three voltmeters $V_0$, $V_1$ and $V_2$, together with the currents $I_0$, $I_1$ and $I_2$, are also shown. Which row gives the values of the current $I_0$ and the potential difference $V_0$?
- A$I_0$ is equal to $I_1$; $V_0$ is equal to $V_2$
- B$I_0$ is equal to $I_2$; $V_0$ is equal to the sum of $V_1$ and $V_2$
- C$I_0$ is equal to the sum of $I_1$ and $I_2$; $V_0$ is equal to $V_1$
- D$I_0$ is equal to the sum of $I_1$ and $I_2$; $V_0$ is equal to the sum of $V_1$ and $V_2$
