Which one of the following statements is not correct?

$A$ diode is connected in parallel with a resistance $R$ as shown in the figure. The most probable current $(I)$ - voltage $(V)$ characteristic is:

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:

In the given circuit,the current $(I)$ through the battery will be $..........\,A$.

If a $p-n$ junction is forward biased,then which of the following figures gives the correct direction of current inside the semiconductor?

If the internal resistance of the cell is negligible,then the current flowing through the circuit is: (in $A$)
