Stresses obtained from Boussinesq's theory are considered reasonably satisfactory in foundation engineering because:

• A. they represent stress distribution in homogeneous soil below loaded area
• B. they account for anisotropy of soil properly
• C. they give due regard to plastic behaviour of soils, particularly of settlement analysis
• D. they consider elastic soil medium, and the intensity of allowable stresses below foundations in most cases are quit small and justify elastic solutions
