The correct option is A Phycomycetes
Phycomycetes (lower fungi) are characterised by presence of aseptate coenocytic hyphae. All fungi with septate mycelia are grouped under eumycota (higher fungi). Ascomycetes and basidiomycetes belong to eumycota and have septate mycelia. Deuteromycetes are characterized by presence of septate mycelium. Thus, the correct answer is option A.
