Three identical p-n junction diodes $D_1$, $D_2$ and $D_3$ are connected across a battery as shown in the figure. If the widths of the depletion regions of $D_1$, $D_2$ and $D_3$ are $W_1$, $W_2$ and $W_3$, respectively, then the correct option is:

  • A
    $W_1 > W_2 > W_3$
  • B
    $W_3 = W_1 > W_2$
  • C
    $W_3 > W_2 > W_1$
  • D
    $W_2 > W_1 = W_3$
