Universal Donor and Universal Acceptor is (1) O+ and AB- (2) O- and AB- (3) O+ and AB+ (4) O- and AB+

Answer: (4) O- and AB+

Explanation: The term “Universal Donor” refers to that person who has that specific blood group who can donate blood to all the people (no matter what their blood group is).

The term “Universal Acceptor” refers to that person who has that specific blood group who can accept blood from anymore (no matter what their blood group is).  

Although O is known as the universal blood donor, it is not possible to donate negative blood types to someone with a positive blood group. Because the O– group lacks both antigens for blood groups and antigens for the Rh factor, it is a universal donor.

Because it has no antibodies to A, B, or Rh, AB+ blood is a universal acceptor and may absorb red blood cells from any kind of blood donor.
