B (fair use, the public domain, or netiquette)

Answer 1

Mark can use quotes from any book in his review because it is allowed under fair use

Fair use allows for the critique of art but does not allow for large chunks of a book to be copied. Fair use also applies to motion picture media, as long as significant portions of the movie is not shown (but rather short clips instead).
