Answer: C. Renaming Doodle was certainly not the kindest thing Brother ever did for him. Brother (and Mama and Daddy) limited Doodle by giving him such a belittling name.
It is likely that someone who looks at this excerpt, and any organizer based on it, will conclude that renaming Doodle was not actually a kind act. His brother tells us that no one who hears the name Doodle would expect much from him. Therefore, the name carries a demeaning connotation because it reflects how little the family expects from the child. Moreover, by giving him that name, they are limiting him as they know that people will unfairly judge the child's abilities.
