If a transistor, the emitter, base and collector are respectively

View answer and explanation

Correct option: A

Heavily doped, lightly doped, moderately doped

Option A (Heavily doped, lightly doped, moderately doped) is correct because the emitter needs a high carrier concentration, the base needs minimal recombination, and the collector handles a significant current.
