Match List I (Equipment) with List II (use) and select the correct answer using code given below the lists.

List I	List II
(a) Hydrometer	(i) Determination of shear parameter
(b) Plate load test set up	(ii) Determination of specific gravity
(c) Pycnometer	(iii) Determination of bearing capacity of soils
(d) Direct shear test apparatus	(iv) Grain size distribution tests for clays

Answer: A

The correct matching is (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i).

The hydrometer measures the settling of fine particles in suspension and gives the grain size distribution of clays and silts (a-iv).
The plate load test loads a steel plate at foundation level to find the bearing capacity and settlement of the soil (b-iii).
The pycnometer, a glass jar with a conical cap, is used to find the specific gravity of soil solids (c-ii).
The direct shear apparatus shears a sample along a fixed plane to give the shear parameters c and φ (d-i).

The other options either swap the hydrometer and pycnometer or swap the plate load and direct shear tests.
