The correct answer is A.

An increase in levels of nitrogen and phosphorus can cause eutrophication, which often leads to algal and phytoplankton blooms in the ecosystems and the formation of dead zones or toxins in the water. The excess nitrogen and phosphorus enter the water from agriculture water runoff and sewage release .
