B. (a) - (i) , (b) - (iii) , (c) - (ii) , (d) - (iv)
C. (a) - (iii) , (b) - (iv) , (c) - (i) , (d) - (ii)
D. (a) - (iii) , (b) - (iv) , (c) - (ii) , (d) - (i)

Answer

To solve the problem of matching the organs with their respective diseases, we will analyze each disease and identify the organ responsible for it.

### Step-by-Step Solution:

1. **Identify Addison's Disease:**
- Addison's disease is caused by the underproduction of hormones from the adrenal cortex.
- **Match:** (a) Addison's disease → (iii) Adrenal cortex

2. **Identify Tetany:**
- Tetany is a condition that arises due to low blood calcium levels, which is regulated by the parathyroid gland through the secretion of parathyroid hormone.
- **Match:** (b) Tetany → (iv) Parathyroid

3. **Identify Acromegaly:**
- Acromegaly is caused by an excess of growth hormone, which is secreted by the pituitary gland.
- **Match:** (c) Acromegaly → (i) Pituitary

4. **Identify Myxedema:**
- Myxedema is a condition resulting from hypothyroidism, which is characterized by insufficient production of thyroid hormones (T3 and T4) from the thyroid gland.
- **Match:** (d) Myxedema → (ii) Thyroid

### Final Matches:
- (a) Addison's disease → (iii) Adrenal cortex
- (b) Tetany → (iv) Parathyroid
- (c) Acromegaly → (i) Pituitary
- (d) Myxedema → (ii) Thyroid

### Summary of Correct Combinations:
- (a) - (iii)
- (b) - (iv)
- (c) - (i)
- (d) - (ii)
