The correct Answer is:
To answer the question "ABO blood grouping is based on the presence or absence of _ surface antigens," we can follow these steps: ### Step-by-Step Solution: 1. **Understanding ABO Blood Grouping**: The ABO blood group system classifies human blood into four main types: A, B, AB, and O. This classification is based on the presence or absence of specific antigens on the surface of red blood cells. 2. **Identifying Surface Antigens**: The key surface antigens involved in the ABO blood grouping are A and B antigens. - Blood type A has A antigens on the surface of its red blood cells. - Blood type B has B antigens. - Blood type AB has both A and B antigens. - Blood type O has neither A nor B antigens. 3. **Conclusion**: Therefore, the correct answer to fill in the blank is "A and B" surface antigens. ### Final Answer: ABO blood grouping is based on the presence or absence of **A and B** surface antigens. ---
