Answer

Correct option: D.
All the above.
Fertilizers contain chemicals. High amount of fertilizers leads to increased amounts of chemicals which kill the microroganisms that recycle nutrients which also degrades the soil structure. Fertilizers in soil when transported or carried off by water into water bodies, result in algal blooms in aquatic bodies thus causing eutrophication.
