Agricultural chemicals are the products used in farming to protect crops from pests and to support growth by supplying nutrients. The best choice lists substances like pesticides, herbicides, and fertilizers—classic examples of these chemicals. Pesticides (insecticides, fungicides, etc.) help control pests and diseases, while fertilizers provide essential nutrients to crops. Seeds and soil additives aren’t chemicals in the same sense, and water treatments aren’t typically described as agricultural chemicals used for pest and nutrient management. So, including pesticides, herbicides, and fertilizers best represents what agricultural chemicals encompass.
