Options

C. 7th day
D. 28th day.

Answer

**Step-by-Step Solution:**

1. **Understanding the Menstrual Cycle**: The menstrual cycle is typically around 28 days long and is divided into phases: the follicular phase, ovulation, and the luteal phase.

2. **Hormonal Changes**: During the follicular phase, the levels of hormones such as Luteinizing Hormone (LH) and Estrogen gradually increase. This phase is characterized by the development of ovarian follicles.

3. **Peak Levels**: Around the middle of the menstrual cycle, typically around the 14th day, there is a significant increase in the levels of LH and Estrogen. This is known as the LH surge.

4. **Ovulation**: The LH surge triggers ovulation, which is the release of an ovum from the mature follicle. This is also the time when Estrogen levels are at their highest.

5. **Conclusion**: Based on the hormonal patterns during the menstrual cycle, the levels of LH and Estrogen are highest around the 14th day.

**Final Answer**: The correct option is A. 14th day.
