Correct answer
Explanation
Professor James Moriarty is Sherlock Holmes's arch-nemesis, described by Holmes as 'the Napoleon of crime.' He is a criminal genius who appears in 'The Final Problem' and 'The Valley of Fear.' Irene Adler (Option A) is a memorable character but not a nemesis. Lestrade and Gregson (Options B and D) are Scotland Yard inspectors who sometimes work with Holmes.
