The coefficient of consolidation of clay is given as:
On increasing the liquid limit, the compressibility increases due to which coefficient of compressibility (av) increases which in turn reduces the Cv as Cv ∝ 1/av.
On increasing the liquid limit, the compressibility increases due to which coefficient of compressibility (av) increases which in turn reduces the Cv as Cv ∝ 1/av.

Solution:
Given statements:
S1: As the compaction effort is increased, the maximum dry unit weight of the compaction is also increased.
S2: The co-efficient of consolidation generally increases as the liquid limit of soil increases.
S1: As the compaction effort is increased, the maximum dry unit weight of the compaction is also increased.
Compaction effort refers to the energy applied to compact the soil. The maximum dry unit weight of a compacted soil is the maximum weight of dry soil per unit volume that can be achieved under a specific compaction effort.
During compaction, as the compaction effort is increased, the soil particles are rearranged and packed more closely together. This results in an increase in the dry unit weight of the soil. Therefore, statement S1 is true.
S2: The co-efficient of consolidation generally increases as the liquid limit of soil increases.
Coefficient of consolidation (Cv) is a measure of the rate at which a saturated soil consolidates under an applied load. It depends on the permeability and compressibility of the soil.
The liquid limit of a soil is the moisture content at which the soil changes from a plastic state to a liquid state. It is a measure of the consistency or stiffness of the soil.
Generally, as the liquid limit of soil increases, the soil becomes more cohesive and less permeable. This means that the soil particles are more tightly packed together and there are fewer interconnected void spaces for water to flow through.
As a result, the coefficient of consolidation generally decreases with an increase in the liquid limit of soil. Therefore, statement S2 is false.
Conclusion:
Based on the above analysis, we can conclude that statement S1 is true and statement S2 is false. Therefore, the correct answer is option 'A'.
