The correct answer is A) foreign intervention.
In Japan, militarists were able to establish a dictatorship partly because the country was facing severe economic problems. What had little or no effect on Japan’s economic crisis was foreign intervention.
With no doubt, Japan was severely affected by the Great Depression. This was one of the reasons for the rising of militarism, Japanese exports diminished because people in Western Europe and the United States had no money to buy them. That is when the Japanese military considers the option of expansion to conquer, gain more territory, and get more raw materials. However, foreign intervention had nothing to do with this.
