A. Eosinophils
B. Lymphocytes
C. Neutrophils
D. Monocytes

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for the most abundant type of white blood cells (WBCs).

2. **Define WBCs**: WBCs, or white blood cells, are crucial components of the immune system and are also known as leukocytes.

3. **Classify WBCs**: WBCs can be classified into two main categories:
- **Agranulocytes**: These do not have granules in their cytoplasm and include:
- Monocytes
- Lymphocytes
- **Granulocytes**: These have granules in their cytoplasm and include:
- Neutrophils
- Eosinophils (also known as acidophils)
- Basophils

4. **Identify the Types of WBCs**:
- **Monocytes**: 4-8%
- **Lymphocytes**: 20-30%
- **Eosinophils**: 1-4%
- **Basophils**: 0-1%
- **Neutrophils**: 60-65%

5. **Determine the Most Abundant WBC**: From the percentages provided, neutrophils are the most abundant type of WBC, comprising 60-65% of the total white blood cell count.

6. **Conclude the Answer**: Therefore, the most abundant WBCs are neutrophils.

**Final Answer**: Neutrophils
