Which best explains why settlers in early Japan developed terraces? to water crops during droughts

to prevent flooding of their fields

to allow plants to grow deeper roots

to make more land available for farming

Please this is timed help me please please please

Option B

Explanation:

Terrance farming is practiced in regions of high erosion of soil. Thus, this approach prevents soil erosion and conserved water. Terraces reduced the speed of water as it moves down and hence restricts the force of soil erosion thereby preventing soil erosion to a great extent. This practice also allows very intensive cropping.

Thus, settlers in early Japan developed terraces to prevent flooding of their fields
