Solution

The correct option is A Phosphates
Eutrophication is the phenomenon of nutrient enrichment by nitrogen and phosphorus, of a water body that initially support a dense growth of plants and animal life. Extensive increase of algae growth in water bodies is called water bloom (algal bloom). Due to death of these algae, their organic matter get decomposed which results in the depletion of oxygen and aquatic animals die.
So, the correct answer is 'Phosphates'.
