Question

Which of the following blood group is a universal donor?

• A. $A{B}^{+ve}$
• B. $O^{+ve}$
• C. $A{B}^{-ve}$
• D. $O^{-ve}$

Answer 1

Answer: (D)

$O^{-ve}$

People with type O- negative blood are the universal donor for the whole blood. That means that, anyone can receive this blood type. Being O- negative, this blood group is compatible with all the blood groups, A${}^{+}$and A${}^{-}$ve, B${}^{+}$ve, B${}^{-}$ve, and AB${}^{+}$, AB${}^{-}$ve. And the chances of rejection is the least.
Therefore, the correct answer is option D.
