Laboratory filtration is conducted at constant pressure drop of $200 \text{ kPa}$ on a slurry of $\text{CaCO}_3$ in water at room temperature. The time taken to collect filtrate is shown below: $$\begin{array}{c} \hline \text{Filtrate volume collected } (\text{m}^3) \quad \vert \quad \text{Time } (\text{s}) \\ \hline 1 \times 10^{-3} \quad \qquad \qquad \vert \quad \ \ \ 40 \\ \hline 2 \times 10^{-3} \quad \qquad \qquad \vert \quad \ \ 100 \\ \hline \end{array}$$ The filter area is $0.05 \text{ m}^2$ and viscosity of filtrate is $10^{-3} \text{ Pa s}$. Which one of the following is the filter medium resistance (in $\text{m}^{-1}$)?
