Answer:
I would say that the sentence from the story that foreshadows the evil results of using the monkey's paw is A: As I wished it twsted in my hands like a snake.
Step-by-step explanation:
I chose this first sentence because I think it is the only one that describes an evil and painful action when saying "it twisted in my hands like a snake". By reading this, the reader can almost feel the pain of torture in his/her own body.
