I say the answer is c , because not only are you getting feedback you're also getting a preview of what your going to be reading , so you can ask questions to know what the story will be about , so that you can be focused on the theme. The theme is the most important part of the story !
Although there are many themes of "The Landlady" by author Roald Dahl, one of the main themes is appearance vs reality. The Landlady is very nice and generous towards Billy which causes him to ignore the sinister plot the Landlady is conjuring.
I think for 2 its goodness...depends on how the person acts in the story and just add some quotes from the story which supports your answer hope this helped
