Reason : Running water cuts through the clayey soils and makes deep channels as gullies. This helps to cultivate crops.
Ans : (d) Both assertion and reason are false.
Terraces, out on slopes in forms of steps breaks up the force of the wind, thus preventing erosion. T gullies render cultivation in those lands impossible.
