Answer:
I believe the correct answer is A. I haven't read The Secret Garden, but I believe that would be the best choice!
Step-by-step explanation:
Since the text said, " Perhaps he'll try to throw his pillow at me again..." I don't think it is C because it's not introducing. It may be D, but with this context, I wouldn't think so. With answer B, the person talking is not with anyone, as I can tell.
