The description ( ) is not right for the basic principles and equations of npn transitor.

A. the injection of electrons from the n-type emitter and the collection of the electrons in the collector
B. the width of the base needs to be small compared with the minority carrier diffusion length, so the junctions are close enough to be called interacting pn junctions
C. the electrons injected from the emitter will diffuse across the base region into the B-C space charge region at the forward-active operating mode
D. Both the B-E junction and the B-C junction are forward biased at the forward-active operating mode
