Concept:
Mushrooms are macroscopic fungi, and several species are commercially cultivated for food. Identifying them by their scientific names is standard in agricultural business.
Step 1: Match the most common commercial mushrooms.
White button mushroom (A) is the most widely cultivated mushroom globally, known as *Agaricus bisporus* (IV). Oyster mushroom (D) is *Pleurotus ostreatus* (III).
Step 2: Match the specialty mushrooms.
Shiitake mushroom (B), highly valued in Asian cuisine, is *Lentinus elodes* (I). Paddy straw mushroom (C) is a tropical species named *Volvariella volvacea* (II).
Step 3: Final Matching.
The correct pairing is A-IV, B-I, C-II, D-III, which matches Option (2).
