Answer

To solve the question regarding the pollution of the Ganga river in Kanpur, we need to identify which activity is not a major factor contributing to its pollution. Here’s a step-by-step approach to arrive at the answer:

### Step 1: Identify Major Pollutants
First, we need to understand what activities are known to cause pollution in the Ganga river. Common sources of pollution in rivers include industrial discharge, sewage disposal, agricultural runoff, and religious practices.

### Step 2: Analyze Each Activity
Next, we should analyze the activities listed in the options provided (though not explicitly mentioned in the question) to determine which one is not a significant contributor to the pollution of the Ganga.

1. **Industrial Discharge**: Factories in Kanpur discharge untreated waste into the river, which is a major pollutant.
2. **Sewage Disposal**: A significant amount of sewage from urban areas flows directly into the Ganga.
3. **Agricultural Runoff**: Pesticides and fertilizers used in agriculture can wash into the river, contributing to pollution.
4. **Religious Practices**: Activities such as immersing idols and conducting rituals can also add to the pollution.

### Step 3: Determine the Least Impactful Activity
After analyzing the activities, we need to identify which one is not a major factor. For instance, if one of the options is related to tourism or recreational activities that do not involve waste disposal, it may not be a significant contributor to pollution.

### Step 4: Conclusion
Based on the analysis, we can conclude which activity is not a major factor responsible for the pollution of the Ganga in Kanpur.

### Final Answer
The activity that is not a major factor responsible for the pollution of the Ganga is likely to be one that does not involve waste or pollutants, such as tourism-related activities.
