What term is used for the main conflict that the protagonist faces?

The term that describes the main conflict that the protagonist faces is "Plot." Plot refers to the sequence of events and conflicts that make up a story, which includes the protagonist's challenges and the central conflict driving the narrative. The main conflict typically revolves around the protagonist's goals, desires, or obstacles, and it is essential to the overall structure of the story.

The climax, another term in the options, refers to the turning point or most intense moment in the story, which often arises from the resolution of the primary conflict, rather than defining it. The antagonistic force usually represents the character or force opposing the protagonist, contributing to the conflict but not encompassing the entirety of the conflict itself. The resolution is the conclusion of the story where conflicts are resolved, but it does not describe the main conflict, which is a crucial part of the plot. Therefore, plot accurately encompasses the central conflict faced by the protagonist.
