The plates of a capacitor are charged to a potential difference of $V \, \text{volts}$ and then connected across a resistor. The potential difference across the capacitor decreases exponentially with respect to time. After one second, the potential difference between the plates is $V/3$; then after two seconds from the start, the potential difference between the plates is

  • A
    $V/3$
  • B
    $V/6$
  • C
    $V/9$
  • D
    $2V/3$
