Answer:
A. clarify the resolution.
Step-by-step explanation:
"For tonight was the grand finale, the trial by fire. There really was no doubt now that she would get in. She could not think of anyone who had ever been invited into the high school sorority and failed to get through initiation time. But even so, her case would be quite different. She would see to that."
The excerpt tells us that she (Millicent) was confident that she would not fail to get through initiation time. It assures us that the story's conflict has been dealt with by clarifying the resolution.
Good luck!!
