B. FSH
C. Progesterone
D. Estrogen

Answer

To solve the question regarding what maintains the corpus luteum formed from the remnants of Graafian follicles after ovulation, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Corpus Luteum**:
- The corpus luteum is formed from the Graafian follicle after ovulation. It is a temporary structure that plays a crucial role in the reproductive cycle.

2. **Formation Process**:
- After ovulation, the Graafian follicle transforms into the corpus luteum. This process is essential for the maintenance of early pregnancy.

3. **Hormonal Secretion**:
- The corpus luteum acts as an endocrine gland and primarily secretes the hormone progesterone. This hormone is vital for preparing the uterine lining for potential implantation of a fertilized egg.

4. **Maintenance of the Corpus Luteum**:
- The maintenance of the corpus luteum, especially in the context of pregnancy, is primarily supported by the hormone Human Chorionic Gonadotropin (hCG), which is produced by the developing placenta shortly after fertilization.

5. **Conclusion**:
- Therefore, the corpus luteum is maintained by the hormone hCG, which ensures that it continues to produce progesterone to support the early stages of pregnancy.

### Final Answer:
The corpus luteum formed from the remnants of Graafian follicles after ovulation is maintained by Human Chorionic Gonadotropin (hCG).
