Assertion: The fruits of groundnut are not nuts but underground pods.
Reason: The pods will not develop until the fertilised ovary is pushed under the soil.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that the fruits of groundnut are not nuts but underground pods. This is true because groundnuts (Arachis hypogaea) produce pods that develop underground, which are technically classified as legumes rather than true nuts.

2. **Understanding the Reason**: The reason provided is that the pods will not develop until the fertilized ovary is pushed under the soil. This is also true. After fertilization, the ovary of the flower elongates to form a peg that grows down into the soil, where the pod develops.

3. **Analyzing the Relationship**: We need to determine if the reason is a correct explanation of the assertion. The development of the pod indeed relies on the fertilized ovary being pushed underground, which supports the assertion that the groundnut is not a true nut but an underground pod.

4. **Conclusion**: Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, we conclude that the correct answer is that both A and R are true, and R is the correct explanation of A.

**Final Answer**: Both assertion and reason are true, and the reason is the correct explanation of the assertion.
