In a p-n-p transistor, in the base region, the main stream of current is—

1. Drift of holes
2. Diffusion of holes
3. Drift of electrons
4. Diffusion of electrons

Correct Option: B

In a pnp transistor, in the base region, the main stream of current is diffusion of holes because holes emit from emitter and some hole diffuse in the base region.
