Solution

The correct option is D $\frac{η_{1}}{η_{2}} = \frac{d_{1} t_{1}}{d_{2} t_{2}}$
If $η_{1}$ and $η_{2}$ are the coefficients of viscosity of two liquids, $d_{1}$ and $d_{2}$ their densities and $t_{1}$ and $t_{2}$ the flow times in Ostwald viscometer, then $\frac{η_{1}}{η_{2}} = \frac{d_{1} t_{1}}{d_{2} t_{2}}$ .

Thus, the coefficient of viscosity is directly proportional to the product of density and flow time in Ostwald viscometer respectively.

So, the correct option is $C$
