Why diffusion current why not drift current?

Option B is right because stream means narrow stream current in NPN transistor base region diffusion of holes.

D is the correct answer, because emitter is heavily doped with an electron. These electrons will diffuse into base.

D is the right answer. Electrons from N region will diffuse to base.

Main stream of current in the base of NPN is due to diffusion of electrons from emitter. Hence D is the correct answer.

Electrons will be diffused through base, so D must be the correct answer.

Electrons are majority carriers in N region (emitter) which will diffuse into P region.

Option D is the right answer. (diffusion of e).
Whereas, only In the case of PNP, option B is right.
