The rate at which water can pass through soil particles is called _____.

Answer: C. Permeability of soil

Permeability is the property that defines how easily water or other fluids can flow through the interconnected pores or voids in a soil mass. It is a measure of the soil's ability to transmit water. Coarse-grained soils like sand and gravel have high permeability because they have larger, well-connected pore spaces, while fine-grained soils like clay have very low permeability.
