Read the following statements:
i. When fungus reproduces sexually, two haploid hyphae of compatible mating types come together and fuse
ii. In some fungi the fusion of two haploid cells immediately results in diploid cell
iii. In fungi of class the Ascomycetes and Basidiomycetes, an intervening dikaryotic stage (n + n i.e., two nuclei per cell) occurs
iv. The dikaryotic cell may show the fusion of nuclei to form diploid cell
