Answer:
The correct answer is B) to express a realization that Carrie has.
Step-by-step explanation:
Sister Carrie tells the story of a girl who moved from a small town to the city, narrating her story to fame and her own idea of the American Dream. It was written by American writer and journalist Theodore Dreiser, who was also part of the naturalist school.
The correct answer is letter B, since the last phrase expresses something that the character has already understood, and it is literally written at the beginning when she said "He could not come here," providing the information mentioned in letter B.
