appeasement was a popular policy because european leaders\nwanted hitler to be happy.\nwanted to avoid…

Brief Explanations:

To determine the correct answer, we analyze each option:

• The first option ("wanted Hitler to be happy") is incorrect as appeasement was not about making Hitler happy but about avoiding conflict.
• The second option ("wanted to avoid another war") is correct. After World War I, European leaders were desperate to prevent another devastating war, so they pursued appeasement to satisfy Hitler's demands in the hope of avoiding conflict.
• The third option ("knew that Hitler desired a confrontation") is incorrect. Hitler's intentions were not fully known, and appeasement was an attempt to prevent confrontation, not based on knowing he desired it.
• The fourth option ("had serious economic problems to deal with at home") is not the primary reason for appeasement. The main motivation was avoiding war, not domestic economic issues.

Answer:

B. wanted to avoid another war.
