Solution

The correct option is C High
Degree of swelling for different differential free swell (OFS) are tabulated below
$\begin{matrix} Degree of swelling & DFS, per cent Low & Less than 20 Moderate & 20 to 35 High & 35 to 50 Very high & Greater than 50 \end{matrix}$

Q. Consider the following statements:
1. A differential free swell value of 40% indicates a soil with a high degree of expansiveness.
2. A swelling pressure of less than

20 k N / m^{2}
