The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Types of Cells Listed:** - The question provides four options: erythrocytes, lymphocytes, eosinophils, and thrombocytes. 2. **Analyze Each Cell Type:** - **Erythrocytes (RBCs):** These are red blood cells primarily responsible for transporting oxygen throughout the body. They do not play a direct role in the immune response. - **Lymphocytes:** These are a type of white blood cell crucial for the immune system. They include T-cells and B-cells, which are essential for adaptive immunity. B-cells can differentiate into plasma cells that produce antibodies, while T-cells help in cell-mediated immunity. - **Eosinophils:** These white blood cells are involved in the response to allergic reactions and parasitic infections. They play a role in the immune response but are not the primary cells responsible for the overall immune mechanism. - **Thrombocytes (Platelets):** These are involved in blood clotting and do not have a role in the immune response. 3. **Determine the Correct Answer:** - Based on the analysis, the only cells that are directly involved in the immune mechanism are lymphocytes. Therefore, the correct answer is **lymphocytes (option B)**. **Final Answer:** The cells involved in the immune mechanism are **lymphocytes**. ---
