The principle in the stimulus discusses the possibility that a novel was not influenced by other novels in its genre; (A) discusses a scenario in which a novel is influenced by other novels in its genre. Further, (A) discusses categorizing novels into the appropriate genre, which the stimulus does not discuss.

This is the opposite of the principle illustrated in the stimulus. Instead of showing a scenario in which two things are similar but one did not influence the other, (B) illustrates a scenario in which two things are not similar but one did influence the other.

(C) illustrates the principle that one should look to successful predecessors of its genre to achieve success. The stimulus does not discuss success. Additionally, the stimulus illustrates a scenario in which a work is not influenced by the other works of its genre.

This situation illustrates the principle that when things appear to be similar (a recent film with car chases and other films of the action genre), it is not necessarily the case that one influenced the other; it is possible that both things were influenced by the same source.

(E) gives a requirement for categorizing something as a historical romance novel; the stimulus does not discuss requirements to categorize works into genres.
