C. Monocytes
D. Basophils.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which type of cell macrophages are modified from. The options provided are eosinophils, neutrophils, monocytes, and basophils.

2. **Identifying Macrophages**: Macrophages are a type of white blood cell that plays a crucial role in the immune system. They are known for their ability to engulf and digest cellular debris and pathogens.

3. **Origin of Macrophages**: Macrophages originate from a specific type of white blood cell known as monocytes. Monocytes are produced in the bone marrow and are released into the bloodstream.

4. **Maturation Process**: Once monocytes leave the bloodstream and enter tissues, they undergo a maturation process to become macrophages. This transformation allows them to perform their immune functions effectively.

5. **Conclusion**: Based on the information, macrophages are modified from monocytes. Therefore, the correct answer to the question is option C: monocytes.
