According to me, the right answer is option B.

Pycnometer should be used for coarse grained soil. For fine grand soil if pycnometer is used then kerosin is used instead of water. Because kerosin has good wetting properties.

Torsion balance method for course grained soil.

Pycnometer for both type.
Oven dry for fine grained soil.

Pycnometer method is more suitable for coarsely grained soil rather than fine grained. Because entrapped air in soil mass can be easily removed in case of coarse grained soil.

But for pycnometer test, specific gravity should be known.

Also I think oven dry test will ever give any error for any kind of soil.

Option A is right. I agree with the given answer.

@Vinod.

Here we have to calculate water from soil not from the coarse aggregate. Just because of that we have to use the pycnometer method.

If we use oven dry method then it will also remove the water from coarse aggregates too.

Pycnometer method is more suitable for cohesionless soils.

Why not oven drying method?

Pycnometer method is suitable for fine grained soils.
