Answer - C - One of the major causes of the Global Depression in 1930 was trade tensions that led to high protective tariffs.

Key Takeaway: A great decline in international business occurred in the late 1920s, largely due to immense trade competition between nations. In response, many nations, such as the United States, established strict barriers and trade limits in the form of tariffs in order to protect their domestic manufacturers. All of these things caused a major global depression in 1930.
