The emitter-base junction is reversed biased in \(\mathrm{n}-\mathrm{p}-\mathrm{n}\) transistor.

The emitter injects minority carriers into the base region of the \(\mathrm{p}-\mathrm{n}-\mathrm{p}\) transistor.

The emitter injects holes into the base of the \(\mathrm{p}-\mathrm{n}-\mathrm{p}\) transistor and electrons into the base region of \(n-p-n\) transistor.

The emitter injects holes into the base of \(\mathrm{n}-\mathrm{p}-\mathrm{n}\) transistor.
