German nationalism had begun developing before World War 2. This was the main reason, many joined the Nazi party. So, option 3 is cause of World War II. Then, Hitler always had hatred towards Jews. He blamed them for the World War 1 and then for the economic condition of Germany. So, option 1 is the cause of World War II.
