For example, Roderick says "I must perish in this bounden slave" (Poe, pg9) foreshadows that Roderick will die. Poe also foreshadows Madeline's death because she has a cataleptical disease that makes her sleep for long periods. This is an example because they can't really tell if she dead or just sleeping.
I think it is D, she likely has been in a similar position coz when she talks with Roger she says something like “I’ve been just like you” or something like that.
