Answer:
Mr Dussel accuses Mrs Van Daan of being less fair than Mrs Frank
Step-by-step explanation:
According to the theme, in times of war, people tend to act differently because they are more nervous than usual and end up blaming people for things they are not responsible for or accusing them of what they haven't done.
Therefore, the event that supports the theme "Wartime can bring out the worst in people" is option C where Mr Dussel accused Mrs Van Daan of being unfair.
