The correct option is D Jealousy of the narrator's apparent superiority
Option D is the correct answer. The narrator appeared to be the ideal man, with all his proper manners, virtues, degrees and ambition, which made him superior in Edward's perception. Edward's dislike of the narrator might as well be stemmed from his jealousy. There is no reference of the narrator's high spirits, he doesn't appear to be impulsive or rash in any way, neither is there any indication of his background. Hence, options A, B and C are incorrect.
