B. Estrogen , Progesterone and LH
C. Testosterone , Estradiol and FSH
D. FSH , LH

Answer

To answer the question regarding the hormones collectively known as gonadotropins, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Gonadotropins**: Gonadotropins are hormones that are secreted by the anterior pituitary gland. They play a crucial role in regulating the function of the gonads (testes in males and ovaries in females).

2. **Identifying the Key Gonadotropins**: The two main hormones classified as gonadotropins are:
- **Follicle Stimulating Hormone (FSH)**: This hormone stimulates the growth and maturation of ovarian follicles in females and acts on Sertoli cells in males to support spermatogenesis.
- **Luteinizing Hormone (LH)**: This hormone triggers ovulation in females and stimulates testosterone production in males by acting on Leydig cells.

3. **Role of Gonadotropin-Releasing Hormone (GnRH)**: The secretion of FSH and LH is regulated by Gonadotropin-Releasing Hormone (GnRH), which is released by the hypothalamus.

4. **Conclusion**: Based on the above information, the hormones that are collectively known as gonadotropins are FSH and LH.

### Final Answer:
The set of hormones that are collectively known as gonadotropins are **Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH)**.
