A
All of the above
💡 Explanation:
Water pollution in rivers and lakes is caused by a combination of industrial waste, agricultural runoff, and sewage discharge. Industrial waste contains toxic chemicals that can harm aquatic life and contaminate drinking water. Agricultural runoff carries fertilizers and pesticides into waterways, which can cause algal blooms and fish kills. Sewage discharge releases untreated human waste into rivers and lakes, which can spread diseases and pollute the water.
