To determine which quotation best supports an answer to Part A, we need to know what the answer to Part A is. However, based on the provided quotations, we can analyze them in context.
If Part A deals with themes of isolation, family relationships, or the stress of living in hiding during the war, then quote B ("I don’t know what good it is to have a son. I never see him. He wouldn’t care if I killed myself.") may be the most relevant, as it highlights both a sense of despair and the emotional toll of separation within families in desperate circumstances.
If Part A discusses the struggles of sharing limited resources, then quote C ("He needs more food than the rest of us. He’s used to more. He’s a big man.") could be relevant, as it addresses the challenges and tensions that arise from scarcity during their time in hiding.
Quote A and D may relate to interpersonal dynamics but may not directly address broader themes as strongly.
Therefore, without knowing the specifics of Part A, B seems to strongly reflect emotional turmoil regarding family connections, making it a probable choice. If you could provide the context or focus of Part A, I could make a more accurate recommendation based on that information.
