C Correct answer
Explanation

Joseph Priestley discovered oxygen in 1774 through experiments with mercuric oxide, calling it "dephlogisticated air." While Scheele also discovered it independently around the same time, Priestley published first. However, it was Lavoisier who correctly identified oxygen as an element, understood its role in combustion, and gave it the name "oxygen." Option B is misspelled (Antonie Lavosier should be Antoine Lavoisier).
