(d) None of these

 

Best Answer

(a)     

Soil erosion can be prevented by using measures where the land is not bare but covered. The best way to cover the land is by having a vegetation cover, planting more trees. The roots of the plants hold the soil firmly and the top layer of soil cannot be carried away by the action of wind or water. Thus deforestation by over graving of land should be prevented and efforts should be made to plant more trees so that the land always has a vegetation cover to prevent soil erosion.
