Question

Pollution in rivers like the Ganga is caused by which of the following factors?

• A. Dumping of industrial waste into rivers.
• B. Releasing treated sewage into rivers.
• C. Louder noise.
• D. Transportation.

Answer 1

The correct option is A Dumping of industrial waste into rivers.

Pollution in rivers is primarily caused by the release of waste chemicals and raw untreated sewage into rivers. This is particularly a problem in the Ganga and Yamuna rivers. Excessive use of fertilisers and pesticides can seep into rivers causing pollution.
