MHT CET Physics question

Not in JEE Advanced syllabus

The diffusion current in a junction is

(A)from the -side to the -side
(B)from the -side to the -sideCorrect
(C)from the -side to the -side, if the junction is forward biased and in the opposite direction, if it is reverse biased
(D)from the -side to the -side, if the junction is forward biased and in the opposite direction, if it is reverse biased
