Question

And after seeing, once again, my mother's disappointed face, something inside me began to die.

Answer 1

reveal that the narrator is becoming rebellious

Answer 2

The answer to this question is possibly: B. To show that the narrator is trying to be smarter.  Looking back at the sentence, I can use context clues.  I can specifically look at where the sentence said, "Something inside me began to die."  That is suggesting that the narrator is influenced by her mother's face to allow something to die within her.  In other words, she realizes that she needs to change into a new, better person.  Hope that helps.
