ANS:B - permeability

The property of a soil that permits water to percolate through it is called: Permeability. Permeability is a measure of how easily water (or other fluids) can flow through soil or rock. It is influenced by factors such as particle size, particle shape, pore size distribution, and soil structure. Soils with high permeability allow water to flow through them easily, while soils with low permeability restrict the flow of water.
