The correct Answer is:
To determine the number of true statements among A to E, we will evaluate each statement one by one. ### Step-by-Step Solution: 1. **Statement A**: "Rheumatoid arthritis is an auto-immune disease." - **Evaluation**: This statement is true. Rheumatoid arthritis is indeed classified as an autoimmune disease where the immune system mistakenly attacks healthy cells in the joints. 2. **Statement B**: "During allergy, IgA type antibodies increases in plasma." - **Evaluation**: This statement is false. During allergic reactions, IgE antibodies are typically elevated, not IgA. IgA is more associated with mucosal immunity. 3. **Statement C**: "Injection given to patients of snakebite, possess antibiotics." - **Evaluation**: This statement is true. Antivenom injections used for snake bites can contain antibiotics to prevent secondary infections, although the primary purpose is to neutralize the venom. 4. **Statement D**: "Humoral immunity is because of B-cells." - **Evaluation**: This statement is true. Humoral immunity is mediated by B-cells, which produce antibodies that target specific antigens. 5. **Statement E**: "Interferons are an example of a cytokine barrier." - **Evaluation**: This statement is true. Interferons are indeed a type of cytokine that play a role in the immune response, particularly in providing a barrier against viral infections. ### Summary of Evaluations: - **True Statements**: A, C, D, E (4 statements) - **False Statement**: B (1 statement) ### Conclusion: The total number of true statements is **4**.
