Answer :
The correct answer is option C. "Racism against African Americans by whites was the norm at that time". The novel "Lizzie Bright and the Buckminster Boy" by Gary D. Schmidt is set in 1912 and tells a real story at which residents of Malaga Island are put in a mental hospital and razed their homes. The historical period contributes to the story because racism against African Americans was the norm in 1912, and Turner befriends a black girl, complicating their social situation.
