A working transitor with its three legs ...

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 or `Q` some resistance is seen on the multimeter . Which of the following is true for the transistor ?

A

it is an n-p-n transistor with R as base

B

it is a p-n-p transistor with R as collector

C
