I would say 'A' Incredulous.
Hope i helped!
This seems like more of a personal thing, i can give you some guidance: let's say you believe strongly in a specific political or philosophical view point. when someone breaks this viewpoint how does that make you feel? hope that helps
The protagonists is Scout but following close behind her is her father. Scout is a curious girl and questions all that her dad says. This gives us, the readers, a chance to really immerse ourselves into the story as we follow it alongside Scout. We further connect with her as we are "on the same boat" as her, in the sense that we only discover things as she does in the book, when she does. There is no dramatic irony ( not that i remember)
