D. The cat scratched Amelia because it knows what I know - that Amelia wants my job.
One of the defining traits of an unreliable narrator is that the point of view of a character it offers is insane, lying, or deluded, among other possibilities that make that its storytelling has little or no credibility.
Considering this characteristic, among the available options there is one that states that there is an animal (A Cat) that knows something (That Amelia wanted the job of the narrator), and this information was the reason that caused its to attack (the scratching).
Since cats - or animals in general - are not known to experiment human emotions like jealousy, therefore this situation is the result of an unreliable narration and the correct answer is D. The cat scratched Amelia because it knows what I know — that Amelia wants my job.
