Options

A. A - 4, B - 2, C - 2, D - 3, E - 5
B. A - 2, B - 1, C - 4, D - 3, E - 5
C. A - 4, B - 1, C - 2, D - 3, E - 6
D. A - 2, B - 1, C - 4, D - 5, E - 3

Answer

To solve the problem of matching hormones with their sources of secretion, we will analyze each hormone listed in Column I and identify the correct source from Column II.

### Step-by-Step Solution:

1. **Identify the first hormone: Somatostatin**
- Somatostatin is produced by the delta cells of the islets of Langerhans, which are part of the pancreas.
- **Match:** Somatostatin (A) → Pancreas (2)

2. **Identify the second hormone: Melatonin**
- Melatonin is produced by the pineal gland, which regulates sleep-wake cycles.
- **Match:** Melatonin (B) → Pineal gland (1)

3. **Identify the third hormone: Aldosterone**
- Aldosterone is a corticosteroid hormone produced by the adrenal cortex. It plays a role in regulating sodium and potassium levels in the body.
- **Match:** Aldosterone (C) → Adrenal cortex (4)

4. **Identify the fourth hormone: Erythropoietin**
- Erythropoietin is produced by the kidneys and stimulates the production of red blood cells (RBCs).
- **Match:** Erythropoietin (D) → Kidney (5)

5. **Identify the fifth hormone: hCG (human Chorionic Gonadotropin)**
- hCG is produced by the placenta during pregnancy and is crucial for maintaining the corpus luteum and progesterone production.
- **Match:** hCG (E) → Placenta (3)

### Final Matching:
- (A) Somatostatin → (2) Pancreas
- (B) Melatonin → (1) Pineal gland
- (C) Aldosterone → (4) Adrenal cortex
- (D) Erythropoietin → (5) Kidney
- (E) hCG → (3) Placenta

### Answer:
The final answer is:
- D: A2, B1, C4, D5, E3
