C- Growth of the follicle and oogenesis, D- Ovulation
E - Sudden increase in the levels of LH.

A. ADCEB
B. BACDE
C. ACEDB
D. CADBE

Answer

To arrange the events in the human female reproductive cycle in proper sequence, we can follow these steps:

1. **Secretion of FSH (Follicle Stimulating Hormone)**: The cycle begins with the secretion of FSH from the anterior pituitary gland. This hormone is crucial for initiating the growth of ovarian follicles.

2. **Growth of the Follicle and Oogenesis**: Following the secretion of FSH, the follicles in the ovaries begin to grow, and oogenesis (the development of oocytes) occurs. This is a key phase where the follicles mature.

3. **Sudden Increase in the Levels of LH (Luteinizing Hormone)**: After the follicles have developed, there is a sudden surge in LH levels, which is critical for triggering ovulation.

4. **Ovulation**: The surge in LH leads to ovulation, which is the release of the mature egg from the ovary.

5. **Growth of Corpus Luteum**: After ovulation, the ruptured follicle transforms into the corpus luteum, which is responsible for producing hormones such as progesterone to prepare the uterus for potential implantation.

Thus, the correct sequence of events is:
- A: Secretion of FSH
- C: Growth of the follicle and oogenesis
- E: Sudden increase in the levels of LH
- D: Ovulation
- B: Growth of corpus luteum

### Final Sequence:
A → C → E → D → B
