The correct answer is B) appeasement.
This cartoon is referencing a situation of the 1930s. It was appeasement.
The policy of appeasement implies the tolerance of one nation when the other nation -a rival or enemy nation- is constantly threatening the other nation. That is what mostly Great Britain did with Hitler before World War II.
In the cartoon attached, we can see how Nazi German leader Adolph Hitler is stepping over the spines of other world leaders, and no one is answering to his aggressions.
