B. low FSH, high LH and low estrogen
C. high FSH, low LH and high estrogen
D. high FSH, high LH and high estrogen

Answer

To solve the question "Just prior to ovulation, there is:", we need to analyze the hormonal changes that occur in the menstrual cycle leading up to ovulation.

### Step-by-Step Solution:

1. **Understanding the Menstrual Cycle**: The menstrual cycle consists of several phases, including the follicular phase, ovulation, and the luteal phase. Ovulation typically occurs around the middle of the cycle.

2. **Role of Hormones**:
- **Follicle Stimulating Hormone (FSH)**: This hormone is responsible for the growth and maturation of ovarian follicles. It stimulates the follicles to produce estrogen.
- **Luteinizing Hormone (LH)**: This hormone surges just before ovulation and is crucial for triggering the release of the egg from the ovary.
- **Estrogen**: Produced by the developing follicles, high levels of estrogen signal the brain to increase LH production.

3. **Hormonal Levels Just Prior to Ovulation**:
- As the follicles mature, they produce increasing amounts of estrogen.
- The rising estrogen levels lead to a feedback mechanism that causes a surge in LH.
- FSH levels are also present but are lower compared to LH just prior to ovulation.

4. **Conclusion**: Just prior to ovulation, there is a high level of LH and estrogen, while FSH levels are lower. The correct answer to the question is that there is high LH and high estrogen, with relatively lower FSH.

### Final Answer:
Just prior to ovulation, there is low FSH, high LH, and high estrogen.
