Correct Answer - Option 2 : Medium
Explanation:
Consistency Index: It is defined as a ratio of the difference between the liquid limit and the natural water content of the soil to the plasticity index.
\({I_c} = \frac{{{w_{L - W}}}}{{{I_p}}}\)
Where,
wL = water content at liquid limit
w = Natural water content
Ip = Platicity index
