One way in which the operation of a-n-p-n transistor differs from that of a p-n-p

Options

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