The sentence that uses the verbs correctly is D, since "the Land of the Horses" is the title of the novel (singular), thus the verb following adds a final -s.
A is wrong because of the same reason. "Four dogs and a Girl" is the title of the novel, so it should be followed by has instead of have.
B is wrong because War and Peace is just one novel. Therefore it should be followed by is rather than are.
C is wrong because, again, Lost Cities is the title of the novel, thus singular and should be followed by describes.
