Find the old one from the following.

Options

A. Glucocorticoids , Mineralocorticoids , sexcorticoids
B. Norepinephrine, Epinephrine , Adrenalin
C. Relaxin , Oestrogen , progestogen
D. Insulin , Glucagon , Thymosin

Answer

To solve the question "Find the odd one from the following," we need to analyze the given options and identify which one does not belong with the others based on their origin or function.

### Step-by-Step Solution:

1. **Identify the Options**:
- Option 1: Glucocorticoid, Mineralocorticoid, and Sex Corticoids
- Option 2: Noradrenaline (Norepinephrine) and Adrenaline (Epinephrine)
- Option 3: Relaxin, Estrogen, and Progesterone
- Option 4: Insulin, Glucagon, and Thymosine

2. **Analyze Option 1**:
- Glucocorticoids, Mineralocorticoids, and Sex Corticoids are all hormones produced by the adrenal cortex. They are related in terms of their origin.

3. **Analyze Option 2**:
- Noradrenaline and Adrenaline are hormones produced by the adrenal medulla. They are also related in terms of their origin and function (stress response).

4. **Analyze Option 3**:
- Relaxin, Estrogen, and Progesterone are hormones produced by the ovaries. They are related in terms of their origin as well.

5. **Analyze Option 4**:
- Insulin and Glucagon are hormones produced by the pancreas, while Thymosine is produced by the thymus gland. This option contains a hormone (Thymosine) that is produced by a different gland compared to the other two hormones.

6. **Conclusion**:
- The odd one out is **Option 4**: Insulin, Glucagon, and Thymosine, because Thymosine is produced by the thymus gland, while Insulin and Glucagon are produced by the pancreas.

### Final Answer:
**Option 4: Insulin, Glucagon, and Thymosine** is the odd one out.
