B. Phycomycetes and basidiomycetes
C. Ascomycetes and phycomycetes
D. Phycomycetes and zygomycetes

Answer

A

Explanation

A dikaryon is a fungal cell which has precisely two genetically distinct but allelically compatible nuclei. In the Ascomyota this attribute is most often found in the ascogenous hyphae and ascocarp while the bulk of mycelia remain monokaryotic. In the Basidiomycota this is the dominant phase.
