The answer is A. The character’s language, background, and clothing should align with the historical time period of the story.
Reason
Answer B, with the growth of a character, should happen regardless, but is not specific to historical fiction.
Answer C, though the use of a well-known historical figure is used to portray comedy, comedy is not what the question is referring to.
Answer D, most protagonists are seen as heroic and inspirational, though, the text is asking about how the story could have a setting that is appropriate for the timeline and geographic area where the story is taken place.
Hope this helps!
