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.
<span> A death has just occurred yet she sees signs of new life.
One would expect a much darker scene to set the tone for Mrs. Mallard's grief. However, instead of sorrow, Mrs. Mallard sees her chance for a new life, one free from her husband's. The new life is hers. A life where she gets to make the decisions and choose what she wants without having to think of another person.
