B. oestrogen , progesterone , FSH
C. FSH, progesterone , oestrogen
D. FSH , oestrogen , progesterone

Answer

To determine the correct hormonal sequence in the case of menstruation, we need to understand the phases of the menstrual cycle and the hormones involved.

### Step-by-Step Solution:

1. **Understanding the Menstrual Cycle**:
- The menstrual cycle consists of three main phases: menstruation, the follicular phase, and the luteal phase.
- Menstruation involves the shedding of the endometrial lining.

2. **Identifying the Hormones**:
- **Follicle Stimulating Hormone (FSH)**: Secreted by the pituitary gland, FSH is crucial for the growth and development of ovarian follicles.
- **Estrogen**: Produced by the developing ovarian follicles, estrogen plays a key role in the regulation of the menstrual cycle and prepares the endometrium for potential implantation.
- **Progesterone**: Secreted by the corpus luteum after ovulation, progesterone is important for maintaining the endometrial lining and supporting early pregnancy.

3. **Sequence of Hormonal Release**:
- The cycle begins with the secretion of **FSH**, which stimulates the growth of follicles.
- As the follicles develop, they secrete **estrogen**.
- After ovulation, the ruptured follicle transforms into the corpus luteum, which secretes **progesterone**.

4. **Correct Order**:
- Therefore, the correct hormonal sequence during the menstrual cycle is **FSH → Estrogen → Progesterone**.

5. **Conclusion**:
- Based on the analysis, the correct answer is the fourth option: **FSH, Estrogen, and Progesterone**.
