Right Answer is: B
SOLUTION
The slow rate of consolidation of saturated clays of low permeability may be exacerbated by means of vertical sand drains which provide for radial drainage, resulting in shortening of drainage path. Consolidation is then mainly due to horizontal radial drainage which results in a faster dissipation of excess pore water pressure.
