Options

A. The emitter junction injects minority carriers into the base region of the p-n-p
B. The emitter injects holes into the base of the p-n-p and electrons into the base regions of n-p-n
C. The emitter injects holes into the base of n-p-n
D. The emitter junction is reversed biased in n-p-n

Answer
