Which one of the following blood cells is involved in antibody production ?

Options

A. B-Lymphocytes
B. T-Lymphocytes
C. RBC
D. Neutrophils

Answer

To determine which blood cell is involved in antibody production, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Antibodies**: Antibodies are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses (antigens).

2. **Identify the Types of Blood Cells**: The options given are B-lymphocytes, T-lymphocytes, RBCs (Red Blood Cells), and neutrophils.

3. **Analyze Each Cell Type**:
- **B-lymphocytes**: These are a type of white blood cell that plays a crucial role in the immune response. They are primarily responsible for producing antibodies.
- **T-lymphocytes**: These cells are also white blood cells, but their main function is to help activate B-lymphocytes and regulate the immune response.
- **RBCs**: Red blood cells are responsible for transporting oxygen and carbon dioxide in the blood. They do not produce antibodies.
- **Neutrophils**: These are a type of white blood cell that primarily engage in phagocytosis, meaning they engulf and digest pathogens. They do not produce antibodies.

4. **Conclude the Correct Answer**: Since B-lymphocytes are specifically involved in the production of antibodies, they are the correct answer to the question.

### Final Answer:
The blood cell involved in antibody production is the **B-lymphocyte**.
