I eliminated D because the primary purpose was not about the theoretical perspective. It was more about the possible confirmation of the theoretical perspective. Remember, most of this passage was about empiricism.
Furthermore, the fact it says a theoretician's perspective is very strong. It was always used plural, and no body in particular was mentioned as a theoretician.
C is right because it covers the discussion happening throughout the passage, not just the theoretical one mentioned solely in the first paragraph. I hope that helps.
