Answer

Brief Explanations:

Eutrophication refers to the enrichment of a water body with nutrients, primarily nitrogen and phosphorus. This excess nutrient input triggers excessive algal and plant growth, leading to oxygen depletion in the water. The other options are incorrect: a decrease in nutrients would not cause this overgrowth, and introducing new species is not the direct cause of eutrophication.

Answer:

A. an increase in nutrients
