While researching a topic, a student has taken the following notes:

For centuries in Japan, terraced rice fields (tanada in Japanese) were built by shaping steep hillsides into flat steps.
This traditional farming method allowed farmers to increase arable land.
The Kurumeki tanada in Shizuoka Prefecture, Japan, was developed during the Heian period.
The Heian period (794 CE–1185 CE) was characterized by economic stability and peace.
The Tenjinkoba tanada in Kumamoto Prefecture, Japan, was developed during the Edo period.

The student wants to emphasize a historical similarity between the two rice terraces. Which choice most effectively uses relevant information from the notes to accomplish this goal?

The Kurumeki tanada was developed during the Heian period; meanwhile, the Tenjinkoba tanada was developed during the Edo period.

The Kurumeki and Tenjinkoba tanada are both exemplars of a traditional farming method wherein flat steps are shaped out of steep hillsides.

As was true for the Kurumeki tanada, the Tenjinkoba tanada was developed during a period of economic stability and peace.

Both the Kurumeki and Tenjinkoba tanada were built by shaping steep hillsides into flat steps, a method that increased the amount of arable land available to farmers.
