C. Atherosclerosis
D. Ricket.

Answer

To determine which of the following is not related to bone disorders, we will analyze each option provided in the context of bone health and disorders.

### Step-by-Step Solution:

1. **Understanding Arthritis**:
- Arthritis is a joint disorder characterized by inflammation of the joints. It often involves the depletion of synovial fluid, leading to pain and difficulty in movement. This condition is related to the health of the joints, which are connected to bones.

2. **Understanding Osteoporosis**:
- Osteoporosis is a condition where there is a decrease in bone mass, often due to hormonal changes (like decreased estrogen in older adults). This leads to an increased risk of fractures. Osteoporosis is directly related to bone health.

3. **Understanding Rickets**:
- Rickets is a bone disorder that occurs in children due to a deficiency of vitamin D, leading to improper bone development and deformities. This condition is also directly related to bone health.

4. **Understanding Atherosclerosis**:
- Atherosclerosis is a condition affecting blood vessels, characterized by the deposition of cholesterol and calcium in the arteries, leading to narrowing and stiffening of these blood vessels. This condition primarily affects the cardiovascular system and is not related to bone health.

5. **Conclusion**:
- Among the conditions discussed, atherosclerosis is the only one that is not related to bone disorders. The other three conditions (arthritis, osteoporosis, and rickets) are all related to bone health.

### Final Answer:
**Atherosclerosis is not related to bone disorder.**
