\nThe correct answer is C) Nitrates and phosphates.
\n<\/section>\n
\nCultural eutrophication is the process of nutrient enrichment of water bodies by human activities. The major contaminants from industries, agriculture, and households that cause this are compounds of nitrogen (like nitrates) and phosphorus (like phosphates). These nutrients promote excessive growth of algae and aquatic plants.
\n<\/section>\n
\nSources of nitrates include agricultural runoff (fertilizers), sewage, and atmospheric deposition. Sources of phosphates include detergents (historically), sewage, industrial waste, and agricultural runoff. High concentrations of these nutrients disrupt aquatic ecosystems by leading to algal blooms, oxygen depletion (hypoxia) upon decomposition of dead algae, and loss of biodiversity.
