Explanation
You know that the athlete used to be well-respected because of his work with anti-drug programs. The contrast is that he was working with anti-drug programs while using steroids for years, so a good word for the blank would be hypocritical or dishonest.
Choices (C) and (E) can be eliminated because they are both positive and mean optimistic, and choice (A) does not mean dishonest and is also incorrect. Choice (B) means related to a crime, and does not necessarily mean dishonest. Choices (D) and (F) are the best answers because they both mean deceitful and produce equivalent, appropriate sentences.
Hence options D and F are correct!
