Correct option is B
The compressibility of soil refers to the property of soil by which it undergoes a decrease in volume when subjected to compressive forces. This property is critical in geotechnical engineering for understanding how soil responds under structural loads, especially for foundation design.
Detailed Explanation of Options:
1. Consolidation of soil:
Refers to the gradual expulsion of water from the soil pores under long-term compressive loading. It is a process, not the inherent property itself.
2. Compressibility of soil:
Correct. It is the intrinsic property of soil that measures its ability to decrease in volume under compressive forces.
3. Compression strength of soil:
Refers to the soil's ability to resist compressive forces, not its tendency to reduce in volume.
4. Initial consolidation of soil:
Refers to the early stage of the consolidation process when pore water starts to escape, not the property of the soil itself.
