Which of the following is an agranulocyte ?

Options

A. Basophil
B. Neutrophil
C. Lymphocyte
D. Eosinophil

Explanation

To determine which of the following is an agranulocyte, we need to understand the classification of leukocytes (white blood cells) in the immune system.

### Step-by-Step Solution:

1. **Understand Leukocyte Classification**:
- Leukocytes are categorized into two main types: granulocytes and agranulocytes.
- Granulocytes contain granules in their cytoplasm, while agranulocytes do not.

2. **Identify Granulocytes**:
- Examples of granulocytes include:
- Basophils
- Neutrophils
- Eosinophils

3. **Identify Agranulocytes**:
- Examples of agranulocytes include:
- Lymphocytes
- Monocytes
- Macrophages

4. **Analyze the Given Options**:
- The options provided are:
- Basophil
- Neutrophil
- Lymphocytes
- Eosinophil

5. **Determine the Agranulocyte**:
- From the options, basophils, neutrophils, and eosinophils are all granulocytes.
- The only agranulocyte listed is lymphocytes.

6. **Conclusion**:
- Therefore, the answer to the question "Which of the following is an agranulocyte?" is **lymphocytes**.
