Answer 1

Answer:

The correct option is A) The chemicals in the pesticides could run off into water sources and contaminate them, which would kill many aquatic species.

Explanation:

Although pesticides can be helpful in eliminating the pests which thrive on crop plants, yet the usage of pesticides can be harmful in a number of ways. Increase in the usage of pesticides can be harmful for humans when they utilize food from such crops which is loaded with pesticides.

The toxic pesticides kills the aquatic life present in that lake or river.
