Final answer:
The correct option is A. Papa likely believed that the French and British military would stop the Nazis, as they had pledged support to Poland before World War II commenced.
Step-by-step explanation:
Papa was likely hoping that the French and British military would stop the Nazis. Given the historical context, before the start of World War II, France and England had declared their support for Poland and deemed Nazi Germany's aggression unacceptable.
They pledged to support Poland, thinking their ultimatum would discourage Hitler from further territorial expansion. Unfortunately, their verbal support did not translate into effective military aid, leading to Poland's swift defeat.
