Explanation:
In literature, a character is a person, an animal, a thing or any other type of being in a story that, somehow, helps develop and advance the plot.
A conflict is a struggle between two opposing forces. The most usual types of conflict in literature are character vs character, character vs self, character vs society, or character vs nature. Conflicts can also be external or internal. External conflicts happen between the character and an outside force. An internal conflict takes place in the character's mind.
The setting of a story is the context surrounding it, the time and the place. It involves geographical location, weather, historical period, time of day and/or year. The setting often has the power to influence the characters, especially if the conflict is permeated with social or cultural motivations.
