The correct answer is: a) Rice.
Terrace cultivation is a type of agriculture that is practiced on steep slopes. It involves building terraces on the hillsides to create level areas for growing crops. This type of cultivation is used in many parts of the world, including Arunachal Pradesh.
In Arunachal Pradesh, terrace cultivation is primarily used for growing rice. Rice is a staple food in the region, and it is grown on both small and large farms. The terraces are built using a variety of methods, but they all involve creating a series of steps on the hillside. The steps are then filled with soil and planted with rice.
Terrace cultivation has a number of advantages. It helps to prevent soil erosion, and it allows farmers to grow crops on land that would otherwise be unsuitable for agriculture. However, it also requires a lot of labor and can be expensive to maintain.
The other options are incorrect because:
- Wheat is not a major crop in Arunachal Pradesh.
- Horticultural crops are grown in the region, but they are not the primary focus of terrace cultivation.
- Tea and coffee are grown in Arunachal Pradesh, but they are not grown on terraces.
