Suppose the Cover of an Explicit Romance Novel Depicts a Vulgar

Suppose the cover of an explicit romance novel depicts a vulgar act on its cover. The book is not of great quality, and the author has stated that the book is simply for the entertainment of those who are old enough to read it. The bookstores to which it has been sent refuse to put the book on the shelves, and this the author says is a violation of the First Amendment. Is the author correct?

A) Yes, all books should be taken to have literary value, and as such the book does not fail the SLAPS test.
B) Yes, the book store's refusal to put the book on the shelves is a blatant act of censorship.
C) No, the book clearly fails the conditions established by Miller v. California and the SLAPS test.
D) No, the book is not suitable for children and thus cannot be made available publicly.
