Question

Universal donor and universal acceptor is

• A. O$+$ and AB$-$
• B. O$-$ and AB$-$
• C. O$+$ and AB$+$
• D. O$-$ and AB$+$

Answer 1

Answer: (D)

O$-$ and AB$+$

Blood group O- is universal donor because it neither has antigen for blood group nor it has the antigen for Rh factor. Hence, it will not invoke any immunogenic response. AB+ is universal acceptor because it has both the antibodies, anti-A and anti-B as well as Rh antigen. So, the correct answer is ‘O- and AB+’
