What part of a plot leads up to the climax of a literary work?

The rising action is the part of the plot that develops the story by building tension and leading up to the climax. During this phase, the protagonist faces various conflicts and challenges that propel the narrative forward, engaging the reader and increasing emotional investment in the character's journey. Events during the rising action introduce complications that heighten suspense, making the climax—the turning point of the story—more impactful.

In contrast, exposition lays the groundwork for the story, introducing characters and setting but not moving towards any significant conflict. Falling action occurs after the climax, as it brings resolution and wraps up the story, while denouement is the final part where any remaining loose ends are tied up. Thus, the rising action is crucial for creating the necessary buildup leading to a satisfying climax.
