The ultimate consolidation settlement of a structure resting on a soil

A. Decreases with the increase in the initial voids ratio:
This statement is incorrect. An increase in the initial voids ratio means there is more void space within the soil, which typically leads to greater consolidation settlement because there is more space for the soil to compress.
B. Decreases with the decrease in the plastic limit:
This statement is not directly related to consolidation settlement. The plastic limit is a measure of the soil's plasticity and does not have a direct relationship with the volume change behavior under load.
C. Increases with the increase in the initial voids ratio:
This statement is correct. As the initial voids ratio increases, the soil has more void space to compress, which typically results in greater ultimate consolidation settlement.
D. Increases with the decrease in the porosity of the soil:
This statement is incorrect. A decrease in porosity means there is less void space within the soil, which would typically result in less consolidation settlement.

Consolidated H / initial Height = change in e /( 1+initial e)
Inversely proportional

BCz ultimate consolidation settlement means change in height i.e)∆H.if the initial void ratio (e) is high then expulsion of watere from soil will be more in turns it requires less change height i.e )it has to do less wrk (∆H) to expel the water.....

But I think whereas for compressibility the increase in e also increases the compressible character of soil.

How?
