(d)presence of antibodies in his blood
Attempt This Question
Not attemptedCorrect Answer: (b) lack of antibodies in his blood
Individuals with AB blood possess both A and B antigens on their red cells but lack the corresponding anti-A and anti-B antibodies in their plasma, so they do not attack transfused erythrocytes of any ABO type, making them ‘universal recipients’. Options mentioning absence of antigens or presence of antibodies are incorrect. ([id.scribd.com](https://id.scribd.com/document/731910046/1995?utm_source=openai))
