The correct option is C To suppress communist ideas
After the First World War, Russia began to focus on its own development, and was recognised as the Union of Soviet Socialist Republics or the USSR in 1922. Capitalist countries like Britain feared that more revolutions would happen and communism may spread all across Europe. Britain began to encourage Hitler to go against the USSR and it's communist ideas. Thus Britain contributed to the rise of Hitler and Nazis that led to the Second World War.
