Answer:
C. To emphasize the unfair discrimination draining the narrator of life.
Step-by-step explanation:
Option C is the correct answer.
From the passage, we discover that the narrator reveals that she is not allowed to drink from the same fountain as the other white folks. She is not allowed to use the same restroom as the other white folks. Then she revealed that they all (both black and white) fought during the war and all bled their red blood. But the blacks are the ones being segregated.
She states that they are allowing their own blood to bled dry due to the color of their skin. This reveals that the narrator is emphasizing the unfair discrimination that she and other black folks are experiencing which is draining their lives.
