The holes diffuse from P-region to the N-region in a P-N junction diode because
there is greater concentration of holes in the P-region as compared to N-region
there is greater concentration of holes in the N-region as compared to P-region
the free electrons in the N-region attract them
potential difference facilities such transfer
