The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: The assertion states that "Anatropous ovule is a resupinate ovule." - **Explanation**: An anatropous ovule is indeed a type of ovule where the body is bent such that the micropyle (the opening through which the pollen tube enters) is positioned close to the hilum (the point of attachment of the ovule to the ovary). This bending gives it a characteristic shape that can be described as resupinate. 2. **Understanding the Reason (R)**: The reason states that "The body of the ovule is completely bent with hilum close to micropilar end." - **Explanation**: This statement accurately describes the anatomical structure of an anatropous ovule. In this type of ovule, the entire body is bent, resulting in the hilum being positioned near the micropyle, which is a defining feature of anatropous ovules. 3. **Evaluating the Relationship**: Now we need to determine if the reason correctly explains the assertion. - **Explanation**: Since the reason (R) provides a clear and accurate description of the structure of an anatropous ovule, it supports the assertion (A). Therefore, both the assertion and the reason are true, and the reason correctly explains the assertion. 4. **Conclusion**: Both the assertion (A) and the reason (R) are true, and the reason is correct in explaining the assertion. ### Final Answer: Both A and R are true, and R is the correct explanation of A. ---
