The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion**: The assertion states that the Fallopian funnel (infundibulum) of the oviduct has finger-like projections called fimbriae. - **Explanation**: The infundibulum is indeed the funnel-shaped end of the oviduct that has finger-like projections (fimbriae) which help in capturing the ovum released from the ovary during ovulation. 2. **Understanding the Reason**: The reason given is that the Graafian follicle of the ovary contains a secondary oocyte suspended in a cavity called the antrum. - **Explanation**: The Graafian follicle (also known as the mature follicle) is the structure that contains the secondary oocyte, and it does have a fluid-filled cavity known as the antrum. This is where the oocyte is located before ovulation. 3. **Evaluating the Connection**: While both the assertion and the reason are true statements, we need to evaluate if the reason correctly explains the assertion. - **Explanation**: The assertion relates to the structure and function of the Fallopian funnel, while the reason describes the characteristics of the Graafian follicle. There is no direct connection between the two statements; the reason does not explain why the assertion is true. 4. **Conclusion**: Since both the assertion and the reason are true, but the reason does not provide a correct explanation for the assertion, the answer is that both statements are true, but the reason is not the correct explanation of the assertion. **Final Answer**: Both assertion and reason are true, but the reason is not the correct explanation of the assertion. ---
