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 solve the question "Which one of the following blood cells is involved in antibody production?" we can follow these steps:

### Step 1: Identify the Types of Blood Cells
Blood cells are primarily categorized into three types:
- Red Blood Cells (RBCs)
- White Blood Cells (WBCs)
- Platelets

### Step 2: Understand the Function of Each Type
- **Red Blood Cells (RBCs)**: Their main function is to carry oxygen throughout the body due to the presence of hemoglobin. Therefore, they do not play a role in antibody production.
- **Platelets**: These are involved in blood clotting and help in the healing process of wounds. They also do not produce antibodies.
- **White Blood Cells (WBCs)**: These are crucial for the immune response and are divided into different types, including lymphocytes.

### Step 3: Focus on Lymphocytes
Lymphocytes are a type of WBC and are further divided into:
- **B Lymphocytes (B Cells)**
- **T Lymphocytes (T Cells)**

### Step 4: Determine the Role of B Lymphocytes
B lymphocytes are specifically responsible for the production of antibodies. These antibodies are proteins that help in identifying and neutralizing foreign objects like bacteria and viruses (antigens).

### Step 5: Eliminate Incorrect Options
- **T Lymphocytes**: While they play a vital role in the immune response, they do not produce antibodies.
- **Neutrophils**: These are another type of WBC that primarily fight infections but do not produce antibodies.
- **RBCs and Platelets**: As discussed, these do not have any role in antibody production.

### Conclusion
Based on the above analysis, the only correct answer to the question is **B Lymphocyte**.

### Final Answer
**B Lymphocyte** is the blood cell involved in antibody production.
