`{:(" Column I "," Column II "),("A. Hypothalamic hormone ","I. Skin "),("B. Thyrotropin (TSH)","II. Adrenal cortex "),("C. Corticotrophin ","III. Thyroid "),("D. Gonadotrophins (LS, FSH) ","IV. Gonad "),("E. Melanotrophin (MSH) ","V. Pituitary "):}`

Options

A. A - I, B - II, C - III, D - IV, E - V
B. A - V, B - IV, C - III, D - II, A - I
C. A - V, B - III, C - II, D - IV, E - I
D. A - V, B - II, C - III, D - IV, E - I

Answer

To solve the matching question between Column I and Column II, we will analyze each item in Column I and find the corresponding item in Column II based on the functions and relationships of the hormones mentioned.

### Step-by-Step Solution:

1. **A. Hypothalamic hormone**:
- The hypothalamus releases hormones that act on the pituitary gland. Therefore, it is associated with the **Pituitary** (V).
- **Match**: A - V

2. **B. Thyrotropin (TSH)**:
- Thyroid Stimulating Hormone (TSH) is produced by the pituitary gland and stimulates the thyroid gland to release thyroid hormones. Hence, it corresponds to the **Thyroid** (III).
- **Match**: B - III

3. **C. Corticotrophin**:
- Corticotrophin (ACTH) is released from the pituitary gland and acts on the adrenal cortex to stimulate the release of corticosteroids. Thus, it matches with the **Adrenal cortex** (II).
- **Match**: C - II

4. **D. Gonadotrophins (LH, FSH)**:
- Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH) are produced by the pituitary gland and act on the gonads (testes and ovaries). Therefore, it corresponds to the **Gonad** (IV).
- **Match**: D - IV

5. **E. Melanotrophin (MSH)**:
- Melanocyte-stimulating hormone (MSH) is released from the pituitary gland and acts on the skin to regulate pigmentation. So, it matches with the **Skin** (I).
- **Match**: E - I

### Final Matches:
- A - V (Hypothalamic hormone - Pituitary)
- B - III (Thyrotropin - Thyroid)
- C - II (Corticotrophin - Adrenal cortex)
- D - IV (Gonadotrophins - Gonad)
- E - I (Melanotrophin - Skin)

### Summary of Matches:
- A → V
- B → III
- C → II
- D → IV
- E → I
