Show answer & explanation
Correct answer: D
Answer: Assertion is false; Reason is true. Why the assertion is false: Earthworms are beneficial for agriculture because they mix soil layers and produce vermicompost, which increases soil fertility.
Their activity improves nutrient availability, supporting plant growth rather than harming agriculture.
Why the reason is true: Earthworms break down organic matter and soil into finer particles and produce castings that are rich in nutrients.
They create tunnels that improve soil aeration and water infiltration, making the soil softer and healthier for plants.
Conclusion: The correct logical relationship is that the Assertion is false and the Reason is true. The reason explains why earthworms are beneficial, which contradicts the assertion that they are not good for agriculture.
