Answer: 2. A and C only

Key idea: Separate household products from industrial products.

Aspergillus niger is used for industrial production of citric acid. Not household.
Trichoderma polysporum produces cyclosporin A (immunosuppressant). Not household.
Lactobacillus (curd), Saccharomyces (bread) and Propionibacterium sharmanii (Swiss cheese) are used in foods.
