Solution

The correct option is B Nitrates and phosphates
Due to the discharge of untreated domestic sewage and surface runoff water, having residues of phosphate, nitrate fertilizers, from agricultural fields etc., into neighbouring water bodies, the water bodies become rich in nutrients especially phosphates and nitrates ions. As a result of nutrient enrichment, water bodies become highly productive or eutrophic and this phenomenon is called as eutrophication.
