[D] Toiletries

Answer: D
Notes:

Why this Question) Focus given on sanitization and disinfection during the pandemic. Harmful effects of triclosan highlighted by IIT study. 

Ans) d 

Exp) Option d is correct. 

Triclosan is an ingredient added to many consumer products intended to reduce or prevent bacterial contamination. It is added to some antibacterial soaps and body washes, toothpastes, and some cosmetics.  

Some short-term animal studies have shown that exposure to high doses of triclosan is associated with a decrease in the levels of some thyroid hormones. Other studies have raised the possibility that exposure to triclosan contributes to making bacteria resistant to antibiotics. At this time, we dont have enough information available to assess the level of risk that triclosan poses for the development of antibiotic resistance.
