The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Question**: The question asks for the chemical messengers of immune cells. 2. **Understand the Options**: The options provided include interferons, histamines, and lysozymes. We need to analyze each option to determine which one functions as a chemical messenger. 3. **Analyze Interferons**: Interferons are categorized as cytokines, which are small, soluble glycoproteins. They act as chemical messengers in the immune response, particularly during viral infections. When a virus invades the body, interferons are produced to help coordinate the immune response. 4. **Analyze Histamines**: Histamines are chemicals released by immune cells that primarily cause allergic reactions. While they play a role in the immune response, they are not classified as chemical messengers in the same way as interferons. 5. **Analyze Lysozymes**: Lysozymes are enzymes found in bodily fluids like tears and saliva. They act as antimicrobial agents by breaking down bacterial cell walls. However, they do not function as chemical messengers. 6. **Conclusion**: Based on the analysis, the correct answer to the question is that the chemical messengers of immune cells are **interferons**. ---
