(A)p-section is made positive and n-section negative.
(B)a potential difference is applied across junction making p-section negative and n-section positive.Correct
(C)a potential difference is applied across the junction.
(D)it is impossible.

Answer: (B)

Solution

Reverse bias (p negative, n positive) gives only a negligible leakage current; forward bias (a) gives a
