Answer: D) Independence vs. autonomy.
Explanation: in literature, a conflict is a struggle between opposite forces, usually between a character (the main character or a very important one) and himself (internal conflict), society or another character (external conflict). In the given excerpt we can see a conflict that represents passion vs. restraint (because the speaker doubts whether or not ask a question about something she wanted to know), individual vs. society (because she thinks that is impolite to ask too many questions), and patience vs. eagerness (because she thinks she would know the answer in time). The option that does not represent a central conflict in the excerpt is independence vs. autonomy.
