Final answer:
The most relevant quotations indicating Anne Frank's feelings of not having a close friend are options D, where she divulges her inability to discuss profound matters with her friends and option C, which implies superficial interactions focused on fun.
Step-by-step explanation:
The quotations from Anne Frank: The Diary of a Young Girl that best support the central idea that Anne feels she has no really close friend are option D and option C. Option D: "I can't bring myself to talk about anything but ordinary everyday things. We don't seem to be able to get any closer, and that's the problem." This quote directly reflects Anne's sense of disconnection from her friends because they do not share deep, personal conversations. Option C: "I have family, loving aunts, and a good home. All I think about when I'm with friends is having a good time." Although this quote does not explicitly state her lack of a close friend, the implication is that her interactions are superficial and focused solely on enjoyment, rather than forming meaningful, intimate bonds.
