I believe the correct answer is D. complexity of character.
A is incorrect because realist writers didn't believe in destiny; B is incorrect because not all realist novels have social trials; C is incorrect for the same reason - not all realist novels have tragic events. Therefore I would pick D, because complex characters reflect reality and what exists in our actual lives.
The statement above is based on the assumption that improved labour standards, economic achievement and social security are not always possible. The correct option is A.
