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?                                           [AIEEE 2008]

A) It is a pnp transistor with R as emitter

B) It is an npn transistor with R as collector

C) It is an npn transistor with R as base

D) It is a pnp transistor with R as collector
