The correct option is A False
Afforestation refers to the planting of trees in an area that is not previously forested, that is, where there was no previous tree cover.
Soil erosion is the displacement of the topmost fertile layer of soil by natural forces like wind, water, etc. The roots of trees firmly hold the topmost layer of the soil and do not allow wind or water to carry away the topmost layer of the soil easily. Thus, afforestation reduces soil erosion.
