C the annexation of Austria
Correct answer is:
d) Detente
Detente is that the easing of strained relations, particularly during a political scenario. within the context of the cold war, the drop-off of tensions between the East and West, in conjunction with domestic reform within the Union of Soviet Socialist Republics, worked along to realize the tip of communism in eastern Europe and eventually the Union of Soviet Socialist Republics altogether.
The Nazi Party convince (roughly) 99% of Germans and Austrians to support the annexation of Austria because Hitler made it clear that this land was historically German, and contained people of German blood.
Hope this helps!
