Vedclass · Answer

(C) In an unbiased $p-n$ junction,the diffusion of charge carriers occurs due to the concentration gradient. Charge carriers (holes and electrons) move from a region of higher concentration to a region of lower concentration. Since the $p-$ region has a higher concentration of holes compared to the $n-$ region,holes diffuse from the $p-$ region to the $n-$ region. Therefore,option $(C)$ is correct.

In an unbiased $p-n$ junction,holes diffuse from the $p-$ region to $n-$ region because
