AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion:** - The assertion states that organic farming is very beneficial for farmers to increase crop production. This is true because organic farming practices enhance soil health, promote biodiversity, and can lead to sustainable crop yields. 2. **Understanding the Reason:** - The reason given is that bacteria, fungi, mycorrhizae, and cyanobacteria are better biofertilizers that fix nitrogen and increase soil fertility. This is also true as these microorganisms play a crucial role in enhancing soil quality and fertility, which is essential for healthy crop growth. 3. **Connecting Assertion and Reason:** - Both the assertion and the reason are true statements. The reason provides a scientific basis for the assertion. By using biofertilizers such as bacteria and fungi, organic farming can indeed improve soil fertility and, consequently, crop production. 4. **Conclusion:** - Since both statements are true and the reason supports the assertion, we can conclude that the assertion is correct because of the reason provided. **Final Answer:** Both the assertion and the reason are true, and the reason supports the assertion. ---
