Q. Consider the following:
  1. Paraquat
  2. Glyphosate
  3. Herbicide
Which of the above is/are classified as a Category 2 hazardous chemical by the WHO?

Answer: Only 1
Notes: Paraquat is classified as a Category 2 hazardous chemical by the WHO due to its toxicity and risk of severe health effects upon exposure. Glyphosate, while widely used, is classified differently. Herbicides are a broader category that includes various chemicals used for weed control, but not all are classified as hazardous. Paraquat's severe toxicity leads to strict regulations in many countries.
