For transistor action :
(1)Base, emitter and collector regions should have similar size and doping concentrations.
(2)The base region must be very thin and lightly doped.
(3)The eimtter-base junction is forward biased and base-collector junction is reverse based.
(4)Both the emitter-base junction as well as the base-collector junction are forward biased.

Correct Option: D
For transistor action, the base region must be very thin and lightly doped. Also, the emitter-base junction is forward biased and base-collector junction is reverse biased.
