A.
Constant head permeability test
Answer
B.
Falling head test
C.
Triaxial test
D.
Direct shear test

Answer: Option A

Solution

Answer: Option A
Solution:
The constant head permeability test is ideal for coarse-grained soils (like sands), allowing a steady flow of water to measure hydraulic conductivity accurately.
