2. **Types of White Blood Cells**: White blood cells are classified into two main categories:
- **Granulocytes**: These include neutrophils, eosinophils, and basophils.
- **Agranulocytes**: These include lymphocytes and monocytes.

3. **Origin of Macrophages**: Among the agranulocytes, monocytes are the precursor cells that differentiate into macrophages. When monocytes leave the bloodstream and enter tissues, they mature into macrophages.

4. **Conclusion**: Therefore, the correct answer to the question "Macrophages are derived from" is **monocytes**.
