Answer:
A. Rising action
Explanation:
The sentence is from Chapter IV of "The Story of My Life" by Helen Keller. This part is after the exposition or introduction of the story in which the main characters, and settings is introduced. However now, in chapter IV, the plot has entered into rising action part in which the main conflicts, struggles, efforts are described.
Option B is incorrect because "conflict" is not part of plot of a story.
Option C is incorrect because this sentence is not introducing any character or setting, but it is describing main character's struggles.
Option D is incorrect because this sentence is from chapter IV out of twenty three chapters. So, it cannot be a conclusion. The tone of the sentence too is not concluding. It leaves reader wanting something more to know.
