In "The Diary of Anne Frank", the most supported theme by Mr. Kraler and Miep's gesture of bringing the cake to the annex on New Year's Day is option C. Wartime often brings out great kindness in people.
During the stay of the Franks, the Van Daans and Dussel in the annex, Miep and Mr. Kraler care about them and try to bring them anything they need. In fact, the group's life depends on the continual risks they take. They bring them, mostly food and other things they are asked to. It is due to their Dutch keepers generosity that the group managed to survive the dangers other Jews had to endure. In this way the theme that wartime often brings out great kindness in people is highlighted.
