Which one of the following pairs correctly matches a hormone with 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 regarding which hormone correctly matches with the disease resulting from its deficiency, we can follow these steps:

### Step 1: Understand the Question
We need to identify the correct pair of a hormone and the disease that arises due to its deficiency.

### Step 2: Analyze Each Option
We have four pairs to evaluate:
1. Relaxin - Gigantism
2. Prolactin - Tretinism
3. Parathyroid hormone - Titani
4. Insulin - Diabetes insipidus

### Step 3: Research Each Hormone and Its Related Disease
- **Relaxin**: This hormone is involved in pregnancy and childbirth. Its deficiency does not lead to gigantism; rather, it is related to cervical dystocia.
- **Prolactin**: This hormone is responsible for milk production. Its deficiency is linked to Shihan syndrome, not tretinism.
- **Parathyroid hormone (PTH)**: This hormone regulates calcium levels in the blood. A deficiency in PTH leads to a condition called tetany (not titani, but likely a typographical error in the question).
- **Insulin**: This hormone regulates blood sugar levels. A deficiency in insulin leads to diabetes mellitus, not diabetes insipidus.

### Step 4: Identify the Correct Pair
From the analysis:
- The correct match is **Parathyroid hormone - Tetany**.

### Step 5: Conclusion
Thus, the correct answer to the question is the pair of **Parathyroid hormone and Tetany**.

### Final Answer
**Parathyroid hormone - Tetany** is the correct pair.
