Answer:
B) The fact that Dr. Jekyll “grew pale to the very lips” and developed “a blackness around the eyes” suggests turmoil within himself.
This is the correct option because Dr. Jekyll is reacting to mention of his other self: Mr. Hyde. It is, by all measures, a conflict of character vs. self.
Explanation:
Option A is incorrect because it demonstrates conflict between two characters, Dr. Jekyll and Mr. Utterson.
Option C is incorrect because curiosity is not conflict.
Option D is incorrect because, again, it demonstrates conflict between two characters—Dr. Jekyll and Mr. Utterson.
