The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Menstrual Cycle Phases**: The menstrual cycle consists of several phases: the follicular phase, ovulation, the luteal phase, and menstruation. Each phase is characterized by different hormonal changes. 2. **Identifying Estrogen Secretion**: Estrogen is primarily secreted by the developing follicles in the ovaries. Its levels fluctuate throughout the menstrual cycle, peaking at specific times. 3. **Analyzing the Phases for Peak Estrogen**: - **Follicular Phase**: During this phase, follicles develop, and estrogen levels begin to rise, but they are not at their peak yet. - **Ovulation**: Just before ovulation, estrogen levels are at their highest. This surge in estrogen is crucial as it triggers the release of the luteinizing hormone (LH), which leads to ovulation. - **Luteal Phase**: After ovulation, estrogen levels do rise again, but they do not surpass the levels seen just before ovulation. 4. **Conclusion**: The peak secretion of estrogen occurs just before ovulation, as this is when the estrogen levels are highest in preparation for the release of the ovum. 5. **Final Answer**: Therefore, the correct answer is that peak secretion of estrogen occurs just before ovulation. ---
