Verified by Experts

The correct Answer is:
B
From the given transfer characteristics of a base biased common emitter transsistor, we note that (ii) When `V_(1)=1V` (which is in between 0.6V to 2.V), the transistor circuit is in active state and it used as an amplifier
(iii) When `V_(1)=0.5V` there is no collector current, The transistor is in cut off state. The transistor cirucit can be used as a switch turned off
(iv) When `V_(1)=2.5V` the colloctor current becomes maximum and transistor is in saturation and can be used as switch turned on statc
