It is generally accepted that he was the first to discover oxygen, among a number of prominent scientists (namely his esteemed colleagues Antoine Lavoisier, Joseph Black, and Joseph Priestley). In fact, it was determined that Scheele made the discovery three years prior to Priestley and at least several before Lavoisier. Joseph Priestley relied heavily on Scheele's work, perhaps so much so that _he_would not have made the discovery of oxygen on his own. <sep>, Pronoun: he <sep>, A: Joseph Priestley <sep>, B: Scheele
Output:
A
