Question

The blood group which is the universal acceptor is (i)______ and the one that is universal donor is (ii)______.

• A. (i) AB, (ii) O
• B. (i) O, (ii) AB
• C. (i)A, (ii)B
• D. (i) O, (ii)A

Answer 1

The correct option is A

(i) AB, (ii) O

AB+ is the universal acceptor as the blood group contains A, B and Rh antigens; contains no antibodies in its serum. Blood group O-, on the other hand, is the universal donor as it contains neither antigen A nor B, nor the Rh antigen, and as a result has A, B and Rh antibodies in its serum.
