(B) According to Newton's law of cooling,the rate of cooling is given by $\frac{d\theta}{dt} = \frac{kA}{ms}(\theta - \theta_0)$.Since the masses $m$ are equal and the calorimeters are similar (same surface area $A$ and emissivity $k$),the rate of cooling depends on the specific heat capacity $s$ of the liquids.Specifically,$\frac{d\theta}{dt} \propto \frac{1}{s}$.Therefore,the rate of cooling depends on the specific heats of the liquids.
