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 width 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:

The current / in the circuit shown below is: (All diodes are ideal and identical)

$$ \text { In the circuit shown below, the voltage appearing across the diode } D \text { will be of the form: } $$

Two statements are given below:

A. When the forward bias voltage across a p-n junction diode increases above a certain threshold voltage, the diode current increases significantly.

B. This current is called reverse saturation current.

Choose the correct answer from the options given below:
