Solution
The correct option is D Cell surface carbohydrates
When the physicians perform any transplant, the organ or the tissue is matched with the patient. There are MHC molecules on the surface of the cell which are matched. These molecules are made up of carbohydrates and proteins. The carbohydrate part is outside the cell and the protein part is embedded in the cell membrane. These MHC molecules are antigen recognising and reaction centres which can activate the immune system and reject the transplant. Thus, the correct answer is option B.
