B. Proliferative phase and secretory phase
C. Proliferatives, secretory and menstrual phase
D. Recovery phase, secretory phase and phase of mentrual flow

Answer

**Step-by-Step Solution:**

1. **Understanding the Menstrual Cycle**: The menstrual cycle is a series of hormonal changes that prepare a woman's body for potential pregnancy. It typically lasts about 28 days but can vary.

2. **Identifying the Stages**: The menstrual cycle consists of several key stages:
- **Menstrual Phase**: This is the first phase where the lining of the uterus (endometrium) sheds if there is no fertilization, resulting in menstrual bleeding. During this phase, the levels of hormones like estrogen and progesterone are at their lowest.

- **Proliferative Phase**: Following menstruation, the proliferative phase begins. This phase is characterized by the rebuilding of the endometrial lining. The levels of estrogen and progesterone begin to rise as the follicles in the ovaries mature into tertiary follicles.

- **Ovulation**: This is the phase where a mature egg is released from the ovary. It occurs around the midpoint of the cycle and is triggered by a surge in luteinizing hormone (LH).

- **Secretory Phase**: After ovulation, the secretory phase occurs. The ruptured follicle transforms into the corpus luteum, which secretes hormones (mainly progesterone and estrogen) to maintain the thickened endometrium in preparation for a possible fertilized egg.

3. **Cycle Continuation**: If fertilization does not occur, the corpus luteum degenerates into corpus albicans, leading to a drop in hormone levels and the start of the menstrual phase again, completing the cycle.

4. **Correct Answer**: Based on the stages identified, the correct answer to the question "Stages in menstrual cycle are" is:
- **Proliferative, Secretory, and Menstrual Phase** (Option C).
