Answer

To solve the question regarding the sequence of activities related to female reproductive processes, we will analyze each activity step by step.

### Step-by-Step Solution:

1. **Oogenesis (A)**:
- Oogenesis is the process of formation of female gametes (ova) in the ovaries. It begins during fetal development and continues until menopause. This is the first step in the reproductive cycle.

2. **Ovulation (B)**:
- After oogenesis, the next step is ovulation. Ovulation occurs when a mature ovum is released from the ovary into the fallopian tube. This typically happens once a month during the menstrual cycle.

3. **Milk Secretion (C)**:
- Following fertilization, if pregnancy occurs, the body prepares for lactation. Milk secretion begins in the mammary glands in response to hormonal changes during pregnancy and after childbirth.

4. **Milk Ejection (D)**:
- Finally, milk ejection occurs when the baby suckles at the breast. This triggers the release of oxytocin, which causes the milk to be ejected from the mammary glands for the baby to consume.

### Correct Sequence:
The correct sequence of these activities is:
1. Oogenesis (A)
2. Ovulation (B)
3. Milk Secretion (C)
4. Milk Ejection (D)

Thus, the correct order is A, B, C, D.
