decrease in liquid limit and increase in plasticity index

decrease in liquid limit and no change in plasticity index

decrease in both liquid limit and plasticity index

increase in both liquid limit and plasticity index

A uniform soil has more strength and stability than a non-uniform soil.

A uniform soil has less strength and stability than a non-uniform soil.

Uniformity coefficient does not affect strength and stability.

Uniformity coefficient of a poorly graded soil is more than that of a well graded soil.
