Which one of the following pairs correctly matches a hormone with a disease resulting from its deficiency?

Options

A. Relaxin -Gigantism
B. Prolactin -Cretinism
C. Parathyroid hormone -Tetany
D. Insulin -Diabetes insipidus

Answer

To solve the question about which hormone correctly matches with a disease resulting from its deficiency, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Hormones and Their Functions**:
- Understand the role of each hormone mentioned in the options. For instance, relaxin is involved in pregnancy, thyroid hormones (T3 and T4) regulate metabolism, parathyroid hormone (PTH) regulates calcium levels, and insulin regulates blood glucose levels.

2. **Analyze the Diseases Listed**:
- Look at the diseases mentioned: gigantism, cretinism, titanium, diabetes mellitus, and diabetes insipidus.

3. **Match Hormones with Diseases**:
- **Relaxin and Gigantism**: Gigantism is caused by excess growth hormone, not relaxin. So, this pair is incorrect.
- **Thyroid Hormones and Cretinism**: Cretinism is indeed caused by a deficiency of thyroid hormones (T3 and T4). This pair is correct.
- **Parathyroid Hormone and Titanium**: Titanium (likely a typo for tetany) is caused by a deficiency of parathyroid hormone, which leads to low calcium levels. This pair is also correct.
- **Insulin and Diabetes Mellitus**: Insulin deficiency leads to diabetes mellitus, not diabetes insipidus. This pair is incorrect.

4. **Determine the Correct Answer**:
- From the analysis, we find that the correct matches are:
- Cretinism with thyroid hormones (T3 and T4)
- Tetany with parathyroid hormone (PTH)
- However, since the question asks for a single correct match, we can conclude that the pair of **Thyroid Hormones and Cretinism** is the most direct and commonly recognized match.

5. **Final Conclusion**:
- The correct answer is the pair of **Thyroid Hormones (T3 and T4) with Cretinism**.
