It is C, since , as I read from a scientific paper, we have:
"The radionuclide is chemically bonded to a molecule involved in the metabolism of the organ in question and administered to the patient. In this way, the molecule, radio-labeled, will serve as a tracer focusing in the tumor rather than in healthy tissues (uptake)."
