The correct answer is A. The point at which the narrator completely identifies herself with the woman trapped in the wallpaper
Step-by-step explanation:
"The Yellow Wallpaper" is a short story that describes the experience of a woman as she is isolated by her husband at an old house as her husband considers she is suffering from depression or a hysterical tendency. During this process, the woman becomes obsessed with the yellow wallpaper in her room.
Indeed, as days pass the woman begins to believe there is a woman behind the wallpaper and at the end of the story when her internal conflict reaches the peak she believes this woman in the wallpaper is herself. This causes the woman to destroy the wallpaper and finally lost her mind completely. This means in this story, the crisis/ climax or higher point in the story is "The point at which the narrator completely identifies herself with the woman trapped in the wallpaper" as this causes the main character to lost her mind.
