Best answer
Right option is (a) homogenous

The best I can explain: In nature, soils are non-homogeneous media, and anisotropic in general. This means that their properties vary within relatively short distances in the vertical and horizontal directions. For the simplicity in solving the equations the soil is considered to be homogenous.
