Answer

To solve the question of which disease is caused by the body attacking its own cells, we will analyze the options provided:

1. **Understanding Autoimmune Disorders**:
- Autoimmune disorders occur when the immune system mistakenly attacks the body’s own cells. This happens when the body fails to distinguish between its own cells and foreign invaders.

2. **Evaluating the Options**:
- **a. Diabetes Insipidus**: This is a condition related to the imbalance of fluids in the body and is not caused by the immune system attacking its own cells.
- **b. Malaria**: This is an infectious disease caused by parasites transmitted through mosquito bites, not an autoimmune disorder.
- **c. Rheumatoid Arthritis**: This is an autoimmune disorder where the immune system attacks the joints, leading to inflammation and pain.
- **d. Tuberculosis**: This is an infectious disease caused by bacteria, not related to the body attacking its own cells.

3. **Identifying the Correct Answer**:
- Among the options, **Rheumatoid Arthritis** is the only condition that fits the definition of an autoimmune disorder, where the body’s immune system attacks its own joint cells.

4. **Conclusion**:
- Therefore, the answer to the question is **c. Rheumatoid Arthritis**.
