00:00The question says, least doped region in a transistor is A, emitter, B, collector, C,

00:16either emitter or collector, D, base is, take a suppose, this is PNP transistor, so this

00:35is emitter, and this is base, and this is collector, A, emitter is heavily doped, and it provides

00:59a large number of majority charge carriers, and base is lightly doped,

01:26and it controls, the flow of current, between emitter and collector, and collector is,

01:54moderately doped, the function of collectors is to collect charges, so the correct option

02:19will be, D, base, means, least doped region in a transistor is base.
