Answer :
In the excerpt from "The Strange Case of Dr. Jekyll and Mr. Hyde," the part that reveals the conflict of character vs. self is:
The fact that Dr. Jekyll "grew pale to the very lips" and developed "a blackness around the eyes" suggests turmoil within himself.
This description of Dr. Jekyll's physical reactions indicates an internal struggle or conflict within his own character. The change in his demeanor, with his face growing pale and eyes darkening, hints at the inner turmoil he is experiencing. It shows that there is a conflict between different aspects of his personality or identity, which is a central theme in the novella. This internal struggle between Dr. Jekyll and Mr. Hyde is a key element in the story and is symbolized by the physical manifestations of distress seen in Dr. Jekyll's reactions in this passage.
