Solution
The correct option is D Terrace farming
Contour barrier and terrace farming are two techniques which can be used to conserve soil.
Contour barriers are made by building barriers along points that are of the same height on mountain slopes using natural materials. Trenches can be dug in front of the barriers to collect water to slow it down.
In terrace farming, flat lands are carved out on the slopes to reduce the speed and amount of soil runoff. These lands can be used for cultivation as well.
