Solution

The correct option is A pnp transistors
The base-collector terminals of the pnp transistor are always reversed biased, then the negative voltage must be used for the collector. Therefore, the base terminal of the pnp transistor must be negative with respect to the emitter terminal, and the collector must be negative than the base.
