Answer: A.Overuse of pesticides
Explanation:
In the agricultural field to prevent the crops from damage caused by the disease causing pests special chemical formulations called as pesticides are added to the agricultural field. These pesticides although protecting the plants from disease causing pests also add up chemicals and toxins to the plants and the crops which if consumed by the human population can cause deadly diseases, allergies, malnourishment and disorders.
Some farmers overuse pesticides in their field without knowing the actual concentration to be used. Therefore, the impacts of ill-effects of the chemicals and toxins will increase in the human or animal population.
