B. 2)insulin-diabetes insipidus
C. 3)adrenaline-hepatitis
D. 4)MSH-metachrosis

Answer

To solve the matching question, we will analyze each option one by one and determine if the pairs are correctly matched based on their definitions and functions.

### Step-by-Step Solution:

1. **Thyroxine with Tetanus**:
- **Thyroxine (T4)**: This is a thyroid hormone produced by the thyroid gland, which regulates metabolism.
- **Tetanus**: This is a condition characterized by painful muscle spasms and is related to calcium metabolism and the parathyroid gland.
- **Conclusion**: Thyroxine is not related to tetanus. **(Incorrect Match)**

2. **Insulin with Diabetes Insipidus**:
- **Insulin**: This hormone is secreted by the pancreas and regulates blood glucose levels.
- **Diabetes Insipidus**: This condition is caused by a deficiency of the antidiuretic hormone (ADH), leading to excessive urination.
- **Conclusion**: Insulin does not relate to diabetes insipidus; it is related to blood sugar regulation. **(Incorrect Match)**

3. **Adrenaline with Hepatitis**:
- **Adrenaline**: This is a hormone produced by the adrenal glands that prepares the body for 'fight or flight' responses.
- **Hepatitis**: This is an inflammation of the liver, often caused by viral infections.
- **Conclusion**: Adrenaline has no relation to hepatitis. **(Incorrect Match)**

4. **MSH with Metacrosis**:
- **MSH (Melanocyte Stimulating Hormone)**: This hormone is secreted from the adenohypophysis (anterior pituitary) and is involved in the regulation of skin pigmentation.
- **Metacrosis**: This refers to the process of shedding or molting in certain animals, which is influenced by MSH.
- **Conclusion**: MSH is indeed related to metacrosis. **(Correct Match)**

### Final Conclusion:
The only correct match is **MSH with Metacrosis**. Therefore, the correct option is **Option 4**.
