Text Solution
Verified by ExpertsThe correct answer is:
C
Region (I) is the cut-off region, region (II) is the active region and region (III) is the saturation region.
If we use the transistor as a switch, the cut-off region (I) is used for OFF state as no current flows at its time and the saturation region (III) is used for ON state as large current flows at this time.
