Dear student 

A good soil is that which allows the water to percolate slowly into groundwater. These soils can remove pollutants and they promote the growth of healthy vegetation, which in turn reduces soil erosion. 

Correct option Is B .

I didn’t get you can you please explain that why not soil which has high absorbing capacity bcoz the more it will absorb the more its nutrients will not leave soil and will stay binded to it?
