If a person has AB- blood, who all can donate blood to him?(a) A+ , B-, O -, AB+(b) A- , B -, O+, AB+(c) A+, B+, O+, AB-(d) A-, B-, O-, AB- |

Answer» Right option is (d) A-, B-, O-, AB- The best I can explain: A person with AB- blood has antigens for A and B and the antibodies for them are absent. Since the blood group is negative, it means that antigen D or the Rhesus factor is also absent in the blood. Thus, all blood groups with negative rhesus factors can donate blood. |
