Answer:
The line that best explains how this passage presents a cultural conflict is - It reveals the narrator's worry over bringing a new lunchbox to school. So, here the right option is Option C.
Explanation:
From the beginning of the passage, it gets clearly demonstrated how the narrator is uncomfortable about a lunchbox he is carrying to school. He is worried about what he would say if he is asked about the meaning of the characters mentioned on the lunchbox.
The unfamiliar smell of the food is also a trigger for his thoughts. All this concern highlights the essence of cultural conflict in the passage. It is evident from the narrator’s words that the other children didn’t accept him and the effect is so drastic that the narrator loses his appetite for his favourite dish which was packed in that lunchbox.
