Single correct option

Consider the following statements about blood groups:
1. A person with blood group O is considered a universal donor.
2. A person with blood group AB is considered a universal recipient.
Which of the statements given above is/are correct?
  1. A. 1 only
  2. B. 2 only
  3. C. Both 1 and 2
  4. D. Neither 1 nor 2
Show answer and solution

Answer: (C) Both 1 and 2

Group O red cells carry neither A nor B antigen, so they are not attacked by antibodies in most recipients, making O the universal donor. Group AB plasma has neither anti-A nor anti-B antibodies, so AB can receive from all groups. Both statements are correct.
