Answer 1

Answer:

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+’

Answer 2

$\Large{\underline{\boxed{\sf{\red{\mathfrak{Universal\:Donors-}}}}}}$

People with O negative blood group do not have A, B or Rh antigen on their RBCs. It means they can donate blood to anyone, as their RBCs will not trigger the immune system of the recipient to fight the blood (as there is no antigen). This is why people with O negative blood group are called universal donors.

$\Large{\underline{\boxed{\sf{\red{\mathfrak{Universal\: Acceptors-}}}}}}$

People with AB blood group do not have antibodies against A or B antigens. It means they can receive any blood type, as their immune system will not fight the antigens present in donor's blood. That is why people with AB blood group are called universal acceptors.
