The V-I characterisctic for a p-n junction diode is plotted as shown in the figure. From the plot we can conclude that
`[V_(b)to` breakdown voltage, `V_(k)to` knee voltage]
A. the forward bias resistance of diode is very high, almost infinity for small values of V and after a certain value it becomes very low
B. the reverse bias resistance of diode is very high in the beginning upto breakdown voltage is not achieved
C. both forward and reverse bias resistances are same for all voltages
D. both (A) and (B) are correct
