Question

Why are people with Type O blood considered universal donors? aTheir erythrocytes have both the A and the B antigens, so their body doesn't make any antibodies bTheir erythrocytes have neither the A nor the B antigen, so there are no antigens to induce an immune response in the recipient cTheir erythrocytes have neither the A nor the B antigen, so their body doesn't make any antibodies dTheir erythrocytes may have the A or the B antigen, so they mutate to conform to the recipient's blood type

Answer 1

The correct answer is the letter B. Their erythrocytes have neither the A nor the B antigen, so there are no antigens to induce an immune response in the recipient

A person with blood type O is considered a universal blood donor because it does not contain A or B antigens; therefore, this blood can be safely donated to people of any blood group.
