Answer:
C. The interplay of the children's names was meant to happen.
Step-by-step explanation:
"The Grasshopper and the Bell Cricket."
"This chance interplay of red and green—if it was chance or play—neither Fujio nor Kiyoko knew about."
Suggesting, the narrator sees the children's names reflected in each other, the color green on the little white kimono and the color red on the other. These contrasting hues and their reflections highlight the barrier between the youngsters and the outside world because of their complimentary nature (they are opposites on the color wheel). The kids don't realize it, but the colors and reflections prove they're related.
