Solution

The correct option is C $Over consolidation ratio.... \sqrt{\frac{Maximum pervious effective pressure}{Existing effective pressure}}$
Coefficient of consolidation,

$C_{v} = \frac{k}{γ_{w} m_{v}} = \frac{T_{v} H^{2}}{t}$

Coefficient of volume compressibility or modulus of volume change,

$m_{v} = \frac{a_{v}}{1 + e_{0}} = \frac{(e_{0} - e)}{(1 + e_{0}) (p - p_{0})}$

Over consolidation ratio,

$= \frac{Maximum previous effective pressure}{Existing effective pressure}$
