Which of the following blood group(s) is/are the universal donor(s)
Answer Details
The correct answer is O.
Blood types are classified based on the presence or absence of certain antigens on the surface of red blood cells. The two most important blood group systems are ABO and Rh.
Blood group O does not have A or B antigens on the surface of its red blood cells. This means that blood group O can be safely transfused into individuals with any blood group (A, B, AB, or O) without causing an adverse immune reaction. Therefore, blood group O is often referred to as the universal donor.
In contrast, individuals with blood group AB have both A and B antigens on the surface of their red blood cells, making them universal recipients. This is because they can safely receive blood from any blood group without the risk of an adverse immune reaction.
Blood groups A and B are not considered universal donors because they contain antigens that can trigger an immune response in individuals with different blood groups.
