Explanation
Option A is incorrect because a higher group index typically indicates poorer soil quality, which usually requires a thicker pavement. Option B is incorrect since a higher CBR value means stronger subgrade, leading to a thinner pavement layer. Option C is correct as the group index values vary from 0 to 20. Therefore, option C is the accurate statement.
