Answer:
A. Josephine wants her to open the door.
Explanation:
The given question refers to The Story of an Hour, a short story written by Kate Chopin. It tells about Louise Mallard, who receives the news that her husband, Brently Mallard, has died. At first, she grieves but then realizes that she is happy that her husband is gone because she is now free. However, it soon turns out that her husband is alive, and he quickly returns home. Her joy turns to shock at the sight of him, which results in her death.
In literature, an external conflict is a struggle that takes place between the main character and some outside force - e.g. other character or society. The external conflict Mrs. Mallard faces is Josephine, her sister, wanting her to open the door. Josephine is concerned about her health, but Louise wants her to go away. We can see this in the following excerpt:
Josephine was kneeling before the closed door with her lips to the keyhold, imploring for admission. "Louise, open the door! I beg; open the door--you will make yourself ill. What are you doing, Louise? For heaven's sake open the door."
"Go away. I am not making myself ill." No; she was drinking in a very elixir of life through that open window.
