One way in which the operation of an `npn` transistor differ from that of a `pnp` transistor is that

A

the emitter junction is reverse biased in `npn`

B

the emitter junction injects minority carriers into the base region of the `pnp`.

C

the emitter injects holes into the base of the `pnp` and electrons into the base region of `npn`

D

the emitter injects holes into the base of `npn`.
