Which of the following statement is correct?
A)The sub-base thickness is directly proportional to the group index of the soil
B)The higher the group index of the soil, the larger is the thickness of the sub-base.
C)If the group index value of the sub-base is between 5 and 9, then the sub-base is poor.

The group index is a value used to evaluate the quality of soil for pavement design, where a higher group index indicates poorer soil quality, necessitating a thicker sub-base to distribute loads effectively. Thus, all the statements correctly describe the relationship between the group index and sub-base thickness or quality.
