To me the correct answer is C. Even if you don't manage to properly define all the variables, you can trace the changes that occur during the experiments and express those as a constant. Then you can adapt the experiments, or perhaps change them, to eventually acquire a complete definition of all the variables. Science history is full of such examples: at first some experiment managed to describe a certain phenomenon in large terms, leaving behind some constants which have been given a better explanation only with further studies.
Think of the difference between the macroscopical and the microscopical gas laws.
