Answer
(a) Universal donor — The blood of O group can be given to all the groups. As blood group O has neither antigen A nor B so it doesn't cause self-clumping with any antibodies making it compatible with all blood groups. Hence, a person with O blood group is called a universal donor.
(b) Universal recipient — A person with blood group AB is called a universal recipient since they can receive blood from a person with any blood group. As blood group AB has no antibodies, so there is no attack on the antigens of any blood group making it compatible to receive blood from all blood groups.
