Water pollution is mainly caused due to:

Options

A. Natural factors
B. Man-made factors
C. Cosmic factors
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Water Pollution**: Water pollution refers to the contamination of water bodies (like rivers, lakes, oceans, and groundwater) due to harmful substances. It can have detrimental effects on the environment and human health.

2. **Identifying Causes of Water Pollution**: The causes of water pollution can be broadly categorized into natural factors, man-made factors, and cosmic factors.

3. **Evaluating Natural Factors**: Natural factors include processes that occur in nature, such as erosion, sedimentation, or natural disasters. These processes typically do not pollute water; instead, they can help in the natural cleaning of water bodies.

4. **Evaluating Cosmic Factors**: Cosmic factors refer to influences from outer space, such as meteorites or cosmic radiation. These factors are not significant contributors to water pollution.

5. **Focusing on Man-Made Factors**: Man-made factors are the primary contributors to water pollution. Human activities such as industrial waste discharge, agricultural runoff (pesticides and fertilizers), sewage disposal, and plastic waste dumping significantly contaminate water bodies.

6. **Conclusion**: Based on the evaluation of the different factors, it is clear that the main cause of water pollution is man-made factors. Therefore, the correct answer to the question is "man-made factors."

**Final Answer**: Water pollution is mainly caused due to man-made factors.
