Answer 1

The correct option is C

The chemical is poisonous and can harm the health of the crop and the consumers.

Insecticides and pesticides are poisonous chemicals that can harm the plants and the consumers. They also pollute the soil where they have been used. Since most of these chemicals are not bio degradable, they stay in the soil and pollute for a very long time.
