Answer 1

The Correct Option is A

Untreated sewage is one of the primary sources of water pollution in India. The discharge of untreated sewage into rivers significantly contaminates the water, making it unsafe for consumption and other uses. Agriculture runoff, unregulated industries, and religious practices also contribute to pollution, but untreated sewage remains the largest contributor.
Thus, the correct answer is (A) Untreated sewage.
