A. directly proportional to time and inversely proportional to drainage path
B. directly proportional to time and inversely proportional to square of drainage path
C. directly proportional to drainage path and inversely proportional to time
D. directly proportional to square of drainage path and inversely proportional to time
Option D is correct as due to submergence, Total weight reduces due to buoyant force acting upwards thus reducing unit weight.
i think option C is also correct. because dry unit weight < bulk unit weight of soil.
