The main reason for water pollution is a. Industrial effluents.

Here's why:

1. Industrial effluents: Industries produce a lot of waste which often gets dumped into rivers and oceans. This waste contains harmful chemicals and heavy metals that pollute the water.

2. Rainwater: Rainwater itself is not a cause of water pollution. However, when it falls on polluted areas, it can carry pollutants into water bodies.

3. Drainage water: Drainage water can contribute to water pollution, especially if it contains sewage or chemicals. However, it is not the main cause.

4. River water: River water is not a cause of water pollution. Instead, rivers can become polluted due to factors like industrial effluents, drainage water, and rainwater carrying pollutants.

So, while rainwater, drainage water, and river water can all be associated with water pollution, the main cause is industrial effluents.
