I believe the answer is B.
Oh boy.
If this is story is planned to end with crazy plot twist i suggest you try to figure that out.
I'm thinking that the girl maybe early adult is living in an apartment with her (insert mental illness) twin and is put into several life threatening scenarios such as car crashes, drugged drinks etc. She doesn't know what is going on but she eventually, though means of spying or accidental, she learns that it's her twin. Maybe some twilight zone hitchhiker he keeps appearing anywhere sort of ordeal. I don't really know what genre you're going for but I think a very realistic interpretation and non-paranormal would be pretty awesome.
I don't have many ideas right now on murder motives besides some sort of schizophrenia or brainwash/temptation. But the story sounds great.
Best of luck!
Answer:
A weird story that happened in my lifetime was when I was let's say 5. when I was five I was walking with my older sister and then we came upon this box. my sister being a chicken did not want me to touch it but I didn't listen. I walked over and opened, it inside I saw that someone had left a little fox cub in it. It was pawing the side of the box crying trying to get out. I called my sister over and said look a puppy. At the time I didn't know that it was a fox. she told me that it wasn't a puppy but a fox instead. I begged to let me take it home and she said I could take it with me if I could carry it all by myself. so I picked the box up and started walking home. The weird part was that the mom of the fox came to our house the next morning and was trying to get to her baby. That was my weird experience.
