Answer:
C. the voiceover narration of the narrator's thoughts
Step-by-step explanation:
The aspect of "The Yellow Wallpaper" that would be easiest to portray in a movie rather than a live performance is the voiceover narration of the narrator's thoughts. In "The Yellow Wallpaper," the narrator's thoughts are described in the first-person point of view, and they are an important part of the story. In a live performance, it would be difficult to convey these thoughts directly to the audience, but in a movie, they could be easily shown through voiceover narration.
