Final answer:
The end of Pixar's 'Up' represents the denouement, a part of the falling action that occurs after the climax, where the plot is resolved and the characters reflect on their experiences.
Step-by-step explanation:
At the end of Pixar's Up, the events that entail Kevin being reunited with her chicks, Russell receiving his 'Assisting the Elderly' badge, and the establishment of a strong friendship between Carl and Russell, best describe the denouement of the film.
This is the part of the story following the climax, where the various strands of the plot are drawn together and matters are explained or resolved, known as the falling action. During the falling action, things start to wind down and characters come away from the climactic experience changed. This leads directly to the denouement which wraps up the narrative and leads to the story's resolution.
