A) (i) and (iii)
B) (i) and (ii)
C) (ii) and (iii)
D) (i), (ii) and (iii)
Correct Answer: A
Solution :
Vetiver grass (Vetiveria zizanioides) is widely grown to prevent soil and moisture conservation. It binds the soil properly. To check wind erosion, planting of trees in the opposite direction of the wind has been taken into consideration. Planting of trees in the opposite direction of the wind reduces the intensity of wind and hence prevents soil erosion. Increasing use of cover crops, such as rye and wheat, have been practiced to reduce soil erosion.
