The correct Answer is:
To determine which blood group is termed as the Universal Donor, we can follow these steps: ### Step-by-Step Solution: 1. **Understand Blood Groups**: Blood groups are classified based on the presence of specific antigens on the surface of red blood cells (RBCs). The main blood groups are A, B, AB, and O. 2. **Identify Antigens**: - Blood group A has antigen A. - Blood group B has antigen B. - Blood group AB has both antigens A and B. - Blood group O has no antigens. 3. **Determine Compatibility**: - Blood group A can donate to A and AB. - Blood group B can donate to B and AB. - Blood group AB can donate only to AB. - Blood group O can donate to A, B, AB, and O. 4. **Identify the Universal Donor**: - Since blood group O has no antigens, it does not trigger an immune response in recipients with any other blood group. Therefore, it can be safely donated to any blood type. 5. **Conclusion**: Based on the compatibility analysis, the blood group that is termed as the Universal Donor is O. ### Final Answer: The blood group which is termed as Universal donor is **O**. ---
