Best answer

Correct option (b) Saturation

Explanation :

VBE=0.7V

Input junction (base emitter) junction is forward biased since VBE=0.7

We should find the condition of output junction i.e. C – B junction

Note,

Thus, collector base junction is forward biased (since collector is –ve with respect base)

Thus, transistor is in saturation
