Which of the following is a correct match between disease and its respective cause

Options

A. Gout- Deposition of urea in synovial joints
B. Rheumatoid arthritis - Deficiency of dystrophin protein
C. Osteoporosis - Imbalance between calcitonin and parathyroid hormone levels
D. Rickets - Autoimmune disorder

Answer

To determine the correct match between diseases and their respective causes, we will analyze each option provided in the question step by step.

### Step 1: Analyze Gout
- **Disease**: Gout
- **Cause Given**: Deposition of urea in synovial joints
- **Correct Information**: Gout is actually caused by the deposition of uric acid crystals in the joints, not urea. Therefore, this match is incorrect.

**Hint**: Remember that gout is related to uric acid, not urea.

### Step 2: Analyze Rheumatoid Arthritis
- **Disease**: Rheumatoid Arthritis
- **Cause Given**: Deficiency of dystrophin protein
- **Correct Information**: Rheumatoid arthritis is an autoimmune disorder where the immune system attacks the joints. It is not caused by a deficiency of dystrophin protein. Thus, this match is also incorrect.

**Hint**: Autoimmune disorders involve the immune system attacking the body, not protein deficiencies.

### Step 3: Analyze Osteoporosis
- **Disease**: Osteoporosis
- **Cause Given**: Imbalance between calcitonin and parathyroid hormone levels
- **Correct Information**: Osteoporosis is characterized by weak and brittle bones, often due to long-term calcium deficiency. The hormones calcitonin and parathyroid hormone do play a role in regulating calcium levels in the body. Therefore, this match is considered correct.

**Hint**: Osteoporosis is related to calcium levels and the hormones that regulate them.

### Step 4: Analyze Rickets
- **Disease**: Rickets
- **Cause Given**: Autoimmune disorder
- **Correct Information**: Rickets is caused by a deficiency of vitamin D, leading to softening of bones in children. It is not classified as an autoimmune disorder. Hence, this match is incorrect.

**Hint**: Rickets is linked to vitamin D deficiency, not autoimmune responses.

### Conclusion
After analyzing all the options, the only correct match is:
- **Osteoporosis**: Imbalance between calcitonin and parathyroid hormone levels.

Thus, the answer is option number 3.
