The right answer is the C: The sneering yellow faces. This scornful and offensive characterization of the Burman (or Bamar) spectators that are attending the football match is the one that most clearly shows an imperialistic attitude in the narrator, an English man who is working as a police officer in Burma and has been charged with the task of shooting an elephant that has killed a local. One of the themes of this story by George Orwell is, in fact, British imperialism and the disastrous consequences that it had for the peoples it subjugated and exploited.
