The correct answer is: electrons from the n - type side cross the p - n junction and recombine with holes in the p - type side
Forward bias causes a force on the electrons pushing them from the N side toward the P side. With forward bias, the depletion region is narrow enough that electrons can cross the junction into the p-type material.
