A working transitor with its three legs marked `P, Q and R` is tested using a multimeter No conduction is found between `'P', 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 ?

It is an npn transistor with R as base

It is a pnp transistor with R as collector

It is a pnp transistor with R as emitter
