I see you haven't pasted the question, so I decided to search it up, and I believe your question was, "Sagole was a wealthy man, but he gives away his food to people who are hungry or in need. Which explains how Sagole's actions develop the theme of the story." So, I think your answer would be "It shows that wealth does not excuse selfish behavior."
The answer is B. Seamlessly weaving flashbacks into present-day action, the author creates a unique story of the events that occurred during the Holocaust in Nazi Germany.
