In a properly biased transistor

View answer and explanation

Correct option: D

Emitter-base depletion layer is small but base-collector depletion layer is large

Option D (Emitter-base depletion layer is small but base-collector depletion layer is large) is correct because in a properly biased transistor, the emitter-base junction is forward biased (small depletion layer) and the base-collector junction is reverse biased (large depletion layer).
