Step-by-Step Rigorous Workflow & Mathematical Proof

Step 1

Identify Phycomycetes Representative

Rhizopus stolonifer is commonly known as the black bread mould, growing on stale, moist bread.

Step 2

Identify Basidiomycetes Representatives

Agaricus campestris is the common edible mushroom. Ustilago maydis / nuda causes smut diseases with powdery black spore masses (smut fungus). Puccinia graminis causes black stem rust of wheat (rust fungus).

Step 3

Correlate Pairs

A-III, B-II, C-IV, D-I matches Option (3) uniquely and unambiguously.
