A working transistor with its three legs marked $$P, Q$$ and $$R$$ is tested using a multimeter. No conduction is found between $$P$$ and $$Q$$. By connecting the common (negative) terminal of the multimeter to $$R$$ and the other (positive) terminal to $$P$$ or $$Q$$, some resistance is seen on the multimeter. Which of the following is true for the transistor?

A

It is an npn transistor with $$R$$ as base

B

It is a pnp transistor with $$R$$ as collector

C

It is a pnp transistor with $$R$$ as emitter

D

It is an npn transistor with $$R$$ as collector
