What problem may arise from water pollution?

Answer and explanation

Correct answer: Decline in drinking water quality

Water pollution means that sewage, chemicals, disease-causing organisms, plastics, or other harmful substances enter rivers, lakes, groundwater, or other water bodies. Once these contaminants mix with water, the water may become unsafe for drinking and domestic use. Therefore, option A is correct: drinking-water quality declines, and exposure may increase the risk of diseases such as diarrhoea and other water-borne infections. The pollution can also damage fish and aquatic plants, but those effects are not listed as an option. Improvement in air quality, increased forest cover, and thicker soil layers are not normal consequences of water pollution.
