The correct answer is: D.Fertilizer runoff

When fertilizers containing phosphates are applied to crops, excess nutrients can be washed into nearby waterways through fertilizer runoff. This occurs when water, such as rain or irrigation, moves over the surface of the land, carrying away nutrients (like phosphates) that have not been absorbed by plants. These nutrients are then transported into rivers, lakes, and other water bodies, where they can cause environmental problems such as eutrophication.

Breakdown of terms:

1.Fertilizer runoff: Refers specifically to the runoff of fertilizers, including phosphates, into water bodies. This is the most accurate term for the scenario described.
