In an unbiased p-n junction, the majority charge carriers (that is, holes) in the p-region diffuse into n-region because of
A. the potential difference across the p-n junction
B. the higher hole concentration in p-region than that in n-region
C. the attraction of free electrons of n-region
D. the higher concentration of electrons in the n-region than that in the p-region.
