Part A. Noel seems like an annoyed character. He seemed happy that James stopped talking.
Part B. for Part B, I would say that the text in E would support saying that he was annoyed. (" The boys had grown tired of hearing her exclaim". That shows that he was starting to get annoyed.) And lastly I think that H would also agree that he was annoyed because he seemed to start going on about why this puppy might be here.
