For a transistor to work as an amplifier

View answer and explanation

Correct option: C

It's emitter junction is in forward bias and collector junction is in reverse bias

Option C (It's emitter junction is in forward bias and collector junction is in reverse bias) is correct because this configuration places the transistor in the active region, which is necessary for amplification.
