The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Antibodies**: Antibodies, also known as immunoglobulins, are proteins produced by the immune system in response to pathogens such as bacteria, viruses, or fungi. 2. **Role of Antigens**: When pathogens enter the body, they have specific molecules on their surface called antigens. These antigens trigger the immune response. 3. **Activation of B Cells**: The presence of antigens stimulates the immune system to activate B cells, which are a type of white blood cell involved in the immune response. 4. **Formation of Plasma Cells**: Once activated, B cells differentiate into plasma cells. Plasma cells are specialized cells that produce antibodies. 5. **Types of Antibodies**: Plasma cells can produce different types of antibodies, including IgG, IgA, IgM, IgE, and IgD, each serving a unique function in the immune response. 6. **Conclusion**: Therefore, antibodies are produced by plasma cells, which are derived from B cells. This makes option number 3 the correct answer. ---
