Solution

The correct option is A Two zones of monokaryotic hyphae
In Agaricus before germination or production of spores the hyphae in the gills are monokaryotic and there are two strains namely + and - starins. During germination the two compatible hyphae merge to form dikaryotic mycellium but this structure is short lived and becomes mononuleated. Therefore the right option is "Two zones of monokaryotic hyphae".
