Aspergillus niger is mainly used in industries for producing citric acid, not in making household products. Trichoderma polysporum is used as an antifungal agent in medicine, not in household preparations. On the other hand, Lactobacillus helps in making curd, Saccharomyces cerevisiae is used in baking bread and making alcohol, and Propionibacterium sharmanii helps in cheese production — all of which are household products. Therefore, Aspergillus niger and Trichoderma polysporum are the ones not involved in household product preparation.

Hence, option (3) is correct.
