The answer is The unsorted sand and rock is the least porous. The porousness of a solid material is dependent on the size of holes within it. This can be tested by how quickly, the material can pass a liquid through it. The bigger the holes, the higher the porousness, In this case, the unsorted sand and rock have the smallest holes between its particles.
