Right choice is (c) both horizontal as well as vertical flows and strains

The explanation is: In actual problems of surface loadings, the pore pressure varies in both horizontal and vertical direction. Therefore, in three dimensional consolidation, it involves both horizontal as well as vertical flows and strains.
