Agranulocytes responsible for immune response of the body are

Options

A. basophils
B. neutrophils
C. Eosinophils
D. lymphocytes

Explanation

To answer the question about which agranulocytes are responsible for the immune response of the body, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Agranulocytes**: Agranulocytes are a type of white blood cell that do not have granules in their cytoplasm. The main types of agranulocytes are lymphocytes and monocytes.

2. **Understand the Role of Lymphocytes**: Among the agranulocytes, lymphocytes are specifically known for their role in the immune response. They are crucial for recognizing and responding to antigens, which are substances that provoke an immune response.

3. **Differentiate Between Types of White Blood Cells**:
- **Basophils**: These are granulocytes, not agranulocytes, and they play a role in allergic reactions and inflammation by releasing histamine and heparin.
- **Neutrophils**: These are also granulocytes and are primarily involved in phagocytosis, where they engulf pathogens.
- **Eosinophils**: These are granulocytes that primarily combat parasitic infections and are also involved in allergic responses.

4. **Conclude with the Correct Answer**: Since the question specifically asks for agranulocytes responsible for the immune response, the correct answer is lymphocytes.

### Final Answer:
The agranulocytes responsible for the immune response of the body are **lymphocytes**.
