It can be inferred that Darkness used in the same way by both authors in that " It represents people who want to hurt the other characters." (Option A)
<h3>What is an inference?</h3>
Inference refers the conclusion that is reached after the key points of a text have been rationally examined.
Hence, it is correct to state that Darkness used in the same way by both authors in that " It represents people who want to hurt the other characters."
All the other options seem like good reasons but are not as important as improving your overall skills (from my perspective at least). Hope this helps!
