Which statement best describes the popularity of Uncle Tom's Cabin?

Uncle Tom's Cabin was most popular in the North.

Uncle Tom's Cabin was most popular in the South.

Uncle Tom's Cabin was popular across the United States.

Uncle Tom's Cabin was not popular and few people read it.

I'd say the correct answer is A. Uncle Tom's Cabin was most popular in the North.

B is definitely not correct because the book is about anti-slavery, and there were many slave owners in the South and they hated the book with a burning passion; thus C is also incorrect because the South almost banned the book; D is incorrect as the book was hugely popular in the North, having become an instant bestseller (took the second place after the Bible).
