The answer is: A. The author creates a scene of loneliness.
In the excerpt from "The Strange Case of Dr. Jekyll and Mr. Hyde," by author Robert Louis Stevenson, Dr. Jekyll reflects that he feels completely trapped in his obscure secret and is terrified that the truth becomes known. Due to his now uncontrollable transformation into Mr Hyde, Jekyll also locks himself in his laboratory, which confines him even more away from society.
My first choice would be A. When you read the excerpt, how does it make you feel? That's your first clue to the answer. If they want something book specific, I would choose C.
I bought my brother some gift-wrap for Christmas. I took it to the gift-wrap department and told them to wrap it, but in a different print so that he would know when to stop unwrapping.
