Before checking any of the answer options, it is worth testing whether the scenario described in the question can even happen under the puzzle's rules.
This means the situation described (Ankit ranked first) directly breaks one of the puzzle's fixed rules, so it is not a valid scenario at all. Since the premise itself is inconsistent, none of the specific claims about Sunil, Tony or Priya's rank can be treated as guaranteed conclusions.
So the correct answer is option D, none of these.
