The correct option is C Two dissimilar haploid nuclei
Dikaryotic cells are commonly formed during the sexual reproduction in fungi. The term dikaryon refers to the fusion of the two genetically dissimilar nuclei of two cells belonging to two distinct strains. They are also known as heterokaryons. The two genetic materials fuse and form the zygospore.
Thus, the correct answer is option D.
