Which of the Following Would Explain Why Organ Donors and Organ

Which of the following would explain why organ donors and organ recipients are genetically matched before an organ transplant is performed?

A) The DNA of a person determines the specific antibody a person makes.In the case of an organ transplant,doctors want to ensure the antibody made within the new organ will not react with the antibody made by the recipient.
B) The self-identification markers on the surface of cells are genetically determined.If the surfaces of the donor's cells and the recipient's cells are not similar,the recipient's immune system will probably reject the new organ.
C) Different genetic sequences may cause the donor and the recipient to produce different strains of interferon,which would result in an autoimmune disease.
D) After entering a cell,an antibody molecule will move into its nucleus and will bind to any DNA segment lacking the self-identification sequence.This can cause organ rejection.
