d) it resulted in more people moving to rural areas.

Explanation:

While around 750, 75% of China's population lived north of the river Yangtze, by 1250, 75% of population lived south the river. This migration was possible due to the introduction of quick-ripening strains of rice  from Vietnam suitable for multi-cropping.
