SUBMIT

D

Explanation:

The correct answer that gives a good example of how the same chemical used to help people can harm the environment would be when excess fertilizers run off into rivers and create a dead zone.

Fertilizers are usually applied to crops as an agricultural practice by farmers to enhance the yield of the crops and boost food or raw materials production. However, excess fertilizer gets washed into nearby water bodies and ends up creating a low-oxygen zone that is incapable of supporting lives within the water body - also known as dead zones.

The correct option is, therefore, D.
