Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R

Assertion A: Diffusion current in a p-n junction is greater than the drift current in magnitude if the junction is forward biased.

Reason R: Diffusion current in a p-n junction is from the $$\mathrm{n}$$-side to the p-side if the junction is forward biased.

In the light of the above statements, choose the most appropriate answer from the options given below

A
Both A and R are correct but R is NOT the correct explanation of A
B
A is correct but R is not correct
C
A is not correct but R is correct
D
Both A and R are correct and R is the correct explanation of A
