• A. True
• B. False

Answer 1

The correct option is A True

This statement is true. Accumulation of sewage leads to water pollution and spread of various diseases. Sewage, fertilizers and agricultural run-offs have nutrients which lead to algal bloom, causing oxygen depletion in water bodies. The lower oxygen levels affect the natural ecological balance of rivers and lake ecosystems. The waste water coming from sewage leads to the spread of many diseases.
