Many times in life we do things logical, such as what's right and what's wrong.
B, you need to give the reader basically a reason to read it so you give the hook and the topic of the sentence so basically what the story is going to be about.
The correct answer would be B) No because there is only one negative in the sentence and that would be ''aren't'' since that means are not, so since that's only one, and not two, its not a double.
This is probably more of a soul searching confession than an answer. I do this too. I am always in the look out for new movies, books and quotes of wisdom. I have accumulated such a humongous collection of e-books and movies that I would probably will never be able to finish them if I gave up everything and only binge-watched or binge-read. I keep browsing GoodReads, IMDB, Quora and the likes, for highly rated books , movies, etc.
