Correct option is D
A bipolar junction transistor (BJT) operates in different regions based on the biasing of its two junctions:
Emitter-Base Junction (EBJ):
Forward-biased when the emitter is at a higher potential than the base.
Collector-Base Junction (CBJ):
Reverse-biased when the collector is at a higher potential than the base.
When:
EBJ is forward biased, and CBJ is reverse biased, the transistor operates in the Active Region.
This is the region where the transistor acts as an
amplifier, allowing a small input current at the base to control a larger current flowing between the collector and emitter.
