The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "In basal placentation, the ovary is unilocular." - This means that in plants exhibiting basal placentation, there is only one chamber (or locule) in the ovary. 2. **Understanding the Reason**: - The reason given is that "Basal placentation is found in sunflower." - This indicates that the sunflower plant is an example of a plant that exhibits basal placentation. 3. **Analyzing the Assertion**: - Basal placentation indeed occurs when the ovule is attached at the base of the ovary, and it is typically unilocular. - Therefore, the assertion is true. 4. **Analyzing the Reason**: - It is also true that basal placentation is found in sunflowers (Helianthus annuus). - Thus, the reason is also true. 5. **Evaluating the Relationship**: - The assertion is true, and the reason is true. However, the reason does not explain why the ovary is unilocular in basal placentation. - The reason simply states that sunflowers exhibit this type of placentation without clarifying the relationship to the assertion. 6. **Conclusion**: - Both the assertion and the reason are true, but the reason does not serve as a correct explanation for the assertion. - Therefore, the correct answer is that both the assertion and reason are true, but the reason is not a correct explanation of the assertion. ### Final Answer: Both assertion and reason are true, but the reason is not a correct explanation of the assertion. ---
