C. Between menstruation and luteal phase
D. Between proliferative phase and secretory phase

Answer

### Step-by-Step Solution:

1. **Understanding Ovulation**:
- Ovulation is the process in which an egg is released from the ovary. It is a crucial part of the menstrual cycle and is associated with the maturation of the ovarian follicle.

2. **Identifying the Phases of the Menstrual Cycle**:
- The menstrual cycle consists of several phases:
- **Menstrual Phase**: The shedding of the uterine lining.
- **Proliferative Phase**: The rebuilding of the uterine lining after menstruation.
- **Secretory Phase**: The phase following ovulation where the uterine lining prepares for a potential implantation of a fertilized egg.

3. **Locating Ovulation in the Cycle**:
- Ovulation typically occurs between the proliferative phase and the secretory phase. This is when the mature egg is released from the graphene follicle.

4. **Evaluating the Options**:
- **Option 1**: Between menstruation and the proliferative phase - This is incorrect.
- **Option 2**: Between menstruation and the secretory phase - This is incorrect.
- **Option 3**: Between menstruation and the uterine phase - This is incorrect.
- **Option 4**: Between the proliferative and the secretory phase - This is correct.

5. **Conclusion**:
- Therefore, the correct answer is that ovulation occurs between the proliferative phase and the secretory phase.
