The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion:** - The assertion states that manures and biofertilizers should be used in place of chemical fertilizers. This implies that there are benefits to using organic alternatives over synthetic ones. 2. **Understanding the Reason:** - The reason given is that chemical fertilizers cause pollution by releasing excess nutrients into water bodies. This highlights a significant environmental concern associated with the use of chemical fertilizers. 3. **Analyzing Manures and Biofertilizers:** - Manures and biofertilizers are organic substances that provide nutrients to plants. They are generally non-toxic, biodegradable, and improve soil health without causing pollution. 4. **Analyzing Chemical Fertilizers:** - Chemical fertilizers, while effective for plant growth, can lead to nutrient runoff into water bodies. This excess nutrient release can cause problems such as eutrophication, which leads to algal blooms. 5. **Effects of Eutrophication:** - Algal blooms can deplete oxygen in the water, harming aquatic life. This demonstrates the pollution aspect mentioned in the reason. 6. **Conclusion:** - Both the assertion and the reason are true. The reason accurately explains why the assertion is valid. Therefore, it is correct to say that manures and biofertilizers should be used instead of chemical fertilizers due to the pollution caused by the latter. **Final Answer:** - Both the assertion and the reason are true, and the reason correctly explains the assertion. ---
