The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the specific cells that are responsible for destroying worn-out white and red blood corpuscles, bacteria, and other microorganisms that pass through the liver. 2. **Identifying Key Terms**: The key terms in the question are "destroy," "worn out white and red blood corpuscles," "bacteria," "microorganisms," and "liver." This indicates that we are looking for cells involved in the immune response and phagocytosis within the liver. 3. **Analyzing the Options**: - **Option A: B cells**: These are a type of lymphocyte involved in the immune response, primarily by producing antibodies. They do not directly destroy cells or pathogens through phagocytosis. - **Option B: T cells**: Another type of lymphocyte that helps in the immune response by releasing cytokines. They also do not directly engulf and destroy cells or pathogens. - **Option C: Oxytocin**: This is a hormone involved in childbirth and lactation, not a cell type, so it is irrelevant to the question. - **Option D: Kupffer cells**: These are specialized macrophages located in the liver that play a crucial role in the immune response by phagocytosing (engulfing and destroying) worn-out blood cells and pathogens. 4. **Conclusion**: Based on the analysis, the correct answer is **Kupffer cells** (Option D), as they are specifically designed to destroy worn-out blood cells and microorganisms in the liver. 5. **Final Answer**: The cells which destroy worn-out white and red blood corpuscles, bacteria, and other microorganisms passing through the liver are **Kupffer cells**. ---
