The set hormones that are collectively known as gonadotropins are

Options

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

Answer

To solve the question regarding the hormones collectively known as gonadotropins, we will analyze the options provided and identify the correct set of hormones.

### Step-by-Step Solution:

1. **Understanding Gonadotropins**: Gonadotropins are hormones that stimulate the gonads (testes in males and ovaries in females). The primary gonadotropins are Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).

2. **Analyzing the Options**:
- **Option 1: Oxytocin, FSH, and Luteinizing Hormone**:
- Oxytocin is not classified as a gonadotropin. FSH and LH are gonadotropins.
- Therefore, this option is incorrect.

- **Option 2: Estrogen, Progesterone, and LH**:
- Estrogen and Progesterone are sex hormones produced by the ovaries, not gonadotropins. LH is a gonadotropin.
- Therefore, this option is incorrect.

- **Option 3: Testosterone, Estradiol, and FSH**:
- Testosterone is a male sex hormone, and Estradiol is a form of estrogen. FSH is a gonadotropin.
- Therefore, this option is incorrect.

- **Option 4: FSH, LH, and TSH**:
- FSH and LH are gonadotropins, but TSH (Thyroid Stimulating Hormone) is not classified as a gonadotropin.
- Therefore, this option is incorrect.

3. **Conclusion**: None of the provided options correctly represent the set of hormones that are collectively known as gonadotropins. The correct gonadotropins are FSH and LH, but they were not presented together in any of the options.

### Final Answer:
The correct hormones that are collectively known as gonadotropins are Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). However, since none of the options provided in the question contain both FSH and LH together, we conclude that the options are incorrect.
