Options:

a

b

c

d

Correct Answer:

a

Explanation:

To switch on the transistor the emitter-base junction of a transistor is forward biased while collector-base junction is reversed biased. The cut off voltage for silicon is 1V, so to switch on a silicon transistor a potential difference of 1V approximately is required between the base and emitter.
