What was Japan's naval ratio as a result of the 1930 London Naval Treaty?

The naval ratio established by the 1930 London Naval Treaty was designed to limit naval armaments among the major powers, primarily the United States, Great Britain, and Japan. The correct ratio was set at 10:10:7. This means for every 10 tons of naval ship tonnage that the US and Britain were allowed, Japan was permitted 7 tons.

This agreement arose from concerns about an arms race and aimed to maintain a balance of power in naval capabilities, particularly in the Pacific region. The treaty recognized Japan's status as a significant naval power but deliberately limited its naval expansion compared to the US and Britain.

The other options do not reflect the actual stipulations of the treaty. The ratios would not have been practical, considering the geopolitical context of the time and the goals of the agreements made to curtail potential naval competition. Thus, choosing the correct ratio highlights an understanding of the specific terms agreed upon in the treaty and their implications for international relations during that era.
