Solution
The correct option is C Both A and B. HLA matching or Human Leukocyte Antigen matching, is a process followed during tissue or organ transplant. This process ensures or prevents rejection of the donor's tissue or organ. The compatibility check or score depends on the type of tissue or organ transplanted.
Blood group matching is necessary during transfusion to prevent the RBCs of the donor from being destroyed by the recipient's immune system. This occurs due to the presence or absence of antigen on the RBCs of both the donor and recipient and the antibodies present or absent in the plasma.
