A. All three can be present in the same novel.
There are three types of external conflict and one type of internal conflict that are considered the most common in literature. The three types of external conflict are: character vs. character, character vs. nature, character vs. society. The internal conflict is character vs. self. These types of conflict can all be present in the same novel. For example, in The Outsiders the character vs. character conflict is the Socs vs. the Greaser. The character vs. nature conflict are the kids vs. the fire. The character vs. society conflict is the Greasers vs. how society does not accept their behavior (especially since society overlooks the same behavior from the Socs). An internal conflict is Johnny's decision about whether or not to turn himself in for Bob's death. All of these conflicts add to the overall themes of the novel.
