Solution
The correct option is A Mucor-Dikaryophase
When intervening between plasmogamy and karyogamy, the cells often contain two nuclei or dikaryons (n + n). Such cells are called dikaryotic cells as in ascomycetes and basidiomycetes but mucor is a phycomycetes fungus. So it does not act as dikaryophase.
A body of branching mycelia composed of hyphae and usually unbranching sporangiophores characterizes rhizopus fungi. In ascomycetes, ascocarp contains sac-like structures (asci) that usually bear four to eight ascospores as in Penicillium. Conidia are asexually produced spores that are borne externally to the cells that produce them. In ascomycetes, asexual spores are conidia produced exogenously on the special mycelium called conidiophores. Conidia on germination produce mycelium as in aspergillus.
