Text Solution
Verified by ExpertsThe correct answer is:
B
The diffusion current in a p-n junction arises due to the movement of majority carriers from a region of high concentration to a region of low concentration.
Electrons diffuse from the 
-side (high electron concentration) to the 
-side (low electron concentration).
Holes diffuse from the 
-side (high hole concentration) to the 
-side (low hole concentration).
So, in terms of direction of diffusion current (conventional current):
