Answer:
B. Complex and flawed characters.
Step-by-step explanation:
As the name indicates, Realism focuses on what is real. Realism is a literary and artistic style that tries to reflect reality as accurately as possible. Therefore, Realism tries to stay away from the idealization of society characteristic of other periods, and addresses morally ambiguous and controversial topics. In order to reflect reality, Realism often employs complex and flawed characters that cannot easily be classified as heroes or villains.
