A
Food preservatives
B
Fruit-ripening substances
C
Reused plastic containers
D
Toiletries
Correct Answer
Explanation
Triclosan is an antibacterial and antifungal agent widely used in toiletries such as soaps, toothpastes, and deodorants to prevent bacterial contamination and increase product shelf life. While food preservatives (Option A) are a common source of chemical exposure, they typically utilize substances like sodium benzoate or sorbic acid, as Triclosan is specifically intended for topical or surface disinfection rather than ingestion. The core concept tested is the identification of hazardous chemicals and endocrine disruptors found in everyday consumer goods.
