Which human blood group is known as the universal recipient because individuals possessing it have neither anti-A nor anti-B antibodies in their plasma?

💡 Solution & Explanation

Individuals with blood group AB are universal recipients because their red blood cells carry both A and B antigens, and their plasma lacks antibodies against either A or B. Blood group O individuals are conversely termed universal donors because their red blood cells lack both A and B antigens. The ABO blood group system was discovered by Karl Landsteiner in the early twentieth century.
