The correct option is A Phycomycetes
Hyphae of fungi form a tangled network called a mycelium. It forms the thallus or the body of fleshy fungi. Hyphae that have walls between the cells are called septate hyphae; hyphae that lack walls and cell membranes between the cells are called nonseptate or coenocytic hyphae.
Coenocytic mycelium – Oomycetes, phycomycetes and Zygomycetes
Septate mycelium – Deuteromycetes, Ascomycetes and Basidiomycetes
