Which of the Following Would Explain Why Doctors Are Very

Which of the following would explain why doctors are very careful to match certain DNA sequences in an organ donor to those of an organ recipient in the case of a necessary organ transplant?

A) The DNA of a person determines what specific antibody a person makes. In the case of an organ transplant, you want to make sure that the antibody made in the new organ did not react with the antibody made by the recipient.
B) The structures on the surface of cells are determined by DNA, and if the surfaces of the cells of the donor and the recipient are different, the recipient's immune system may attack the new organ.
C) Different DNA sequences may cause the donor and the recipient to produce different strains of interferon, which would result in an autoimmune disease.
D) Antibodies can travel through cells to the nucleus and will attack DNA that does not have the self sequence. This can cause organ rejection.
