Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for a disease caused by the deficiency of iron.

2. **List the Options**: The options provided are:
- Anemia
- Cholera
- Dysentery
- Merism

3. **Evaluate Each Option**:
- **Anemia**: This is a condition characterized by a lack of healthy red blood cells (RBCs) or insufficient hemoglobin in the blood. Iron is a crucial component of hemoglobin, and its deficiency leads to anemia. Symptoms include dizziness, breathlessness, and fatigue.
- **Cholera**: This is a bacterial disease caused by the bacterium *Vibrio cholerae*. It is not related to iron deficiency.
- **Dysentery**: This is also a bacterial disease, typically caused by *Shigella* species. Like cholera, it is not caused by iron deficiency.
- **Merism**: This refers to a condition resulting from a deficiency of overall nutrients, particularly calories, rather than specifically iron.

4. **Conclusion**: After evaluating all options, the only disease caused by iron deficiency is **Anemia**.

5. **Final Answer**: The disease caused by deficiency of iron is **Anemia**.
