What percentage of China's land is arable?

The correct answer indicates that less than 15% of China's total land area is arable, which aligns with data and studies regarding China's agricultural capacity. Estimates typically range around 10-12% when considering the country's vast geographic size—approximately 9.6 million square kilometers—much of which consists of mountains, deserts, and other non-arable terrains.

China faces significant challenges in increasing its arable land due to urbanization, industrialization, and environmental degradation, which puts pressure on the available agricultural land. This limited percentage poses a challenge for the country as it seeks to feed its large population while ensuring food security. In contrast, the other options suggest higher percentages that do not accurately reflect the reality of China's land use, which is constrained by natural geography and increasing human development.
