Answer

**Step-by-Step Solution:**

1. **Understanding the Menstrual Cycle**: The menstrual cycle is a monthly series of changes a woman's body goes through in preparation for the possibility of pregnancy. It typically lasts about 28 days but can vary from 21 to 35 days.

2. **Identifying the Phases**: The menstrual cycle consists of four main phases:
- **Menstrual Phase**: This is the phase where the uterine lining sheds, leading to menstrual bleeding. It usually lasts from day 1 to day 5 of the cycle.
- **Follicular Phase (Proliferative Phase)**: Following menstruation, this phase involves the thickening of the uterine lining and the maturation of follicles in the ovaries. It generally lasts from day 6 to day 14.
- **Ovulatory Phase**: This phase occurs around day 14, where an egg is released from a mature follicle in the ovary.
- **Luteal Phase (Secretory Phase)**: After ovulation, the body prepares for a possible pregnancy. The ruptured follicle transforms into the corpus luteum, which secretes hormones to maintain the uterine lining. This phase lasts from day 15 to day 28.

3. **Analyzing the Options**: The options provided in the question are:
- A) Recovery phase and proliferative phase
- B) Proliferative and secretary phase
- C) Proliferative, secretary, and menstrual phase
- D) Recovery phase, secretary phase, and the phase of menstrual flow

4. **Determining the Correct Answer**: Based on the phases identified:
- The correct phases are the menstrual phase, proliferative (follicular) phase, and secretory (luteal) phase.
- Therefore, the correct answer is **Option C: Proliferative phase, secretary phase, and menstrual phase**.

**Final Answer**: The stages in the menstrual cycle are: **Option C - Proliferative phase, secretary phase, and menstrual phase.**
