1. In a forward biased pn junction diode, the sequence of events that best describes the mechanism of
current flow is
(A) injection, and subsequent diffusion and recombination of minority carriers
(B) extraction, and subsequent drift and recombination of minority carriers
(C) extraction, and subsequent diffusion and generation of minority carriers
(D) injection, and subsequent drift and generation of minority carriers
