Solution

The correct option is B Six
Intervening Dikaryotic stage is present in Ascomycetes and Basidiomycetes.
Puccinia, Neurospora, Claviceps, Mitchell's, Ustilago and Agaricus belong to these groups and hence have it.
Albugo and Rhizopus belong to other divisions of fungi and do not show this intervening stage.

So, the correct answer is ' Six'.
