B. LH
C. FSH, LH, Estrogen
D. Oxytocin

Answer

To answer the question regarding which hormones mainly control the menstrual cycle in human beings, we can break down the process into several steps:

### Step-by-Step Solution:

1. **Identify the Key Hormones**: The menstrual cycle is primarily regulated by three hormones: Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), and Estrogen.

2. **Role of Follicle Stimulating Hormone (FSH)**:
- FSH is produced by the anterior pituitary gland.
- It stimulates the growth and maturation of ovarian follicles, which contain the eggs.
- This hormone is crucial in the early stages of the menstrual cycle.

3. **Role of Luteinizing Hormone (LH)**:
- LH is also produced by the anterior pituitary gland.
- It plays a key role in triggering ovulation, which is the release of the mature egg from the ovary.
- LH works in conjunction with FSH to regulate the menstrual cycle.

4. **Role of Estrogen**:
- Estrogen is produced by the developing follicles in the ovaries.
- It is responsible for the thickening of the uterine lining (endometrium) in preparation for a potential pregnancy.
- Estrogen levels rise during the follicular phase and peak just before ovulation.

5. **Conclusion**:
- The menstrual cycle is primarily controlled by FSH, LH, and Estrogen.
- Therefore, the correct answer to the question is that these hormones collectively regulate the menstrual cycle.

### Final Answer:
The hormones that mainly control the menstrual cycle in human beings are Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), and Estrogen.
