The correct answer is C. Mark Twain. His realistic dialect is best seen in his novels "The Adventures of Tom Sawyer" and "The Adventures of Huckleberry Finn", with main characters who come from lower social classes, with a distinct and very colorful dialect. His is a regional, rural, non-embellished America, with all its ambiguities and problems. However, his critique of it is often done in a very witty and humorous way. His proverbs are well known and much exploited, such as "I never let schooling interfere with my education," "Man is the only animal that blushes, or needs to," etc.
