a) Angle of internal friction
b) Permeability
c) Adhesion
d) Porosity

Answer: a
Explanation: Angle of internal friction and Cohesion are the soil parameters which are used in analytical method to determine the ultimate bearing capacity of soil. The samples, preferably of undisturbed soil, are collected from the bore holes or test pits and various test are then carried out in the soil testing laboratory for the purpose of analytical analysis of the soil.
