(B) Drift of charge carriers
(C) Doping
(D) Generation of electric field at the junction

Choose the correct answer from the options given below:

(C), (A), (D), (B)

The correct answer is Option (3) → (C), (A), (D), (B)

Correct sequence:

(C) Doping → (A) Diffusion of charge carriers → (B) Drift of charge carriers → (D) Generation of electric field at the junction
