(C) According to the Clausius-Clapeyron equation,the relationship between vapour pressure $(p)$ and absolute temperature $(T)$ is given by:$\log p = -\frac{\Delta H_{vap}}{2.303 R} \cdot \frac{1}{T} + C$Here,$\Delta H_{vap}$ is the enthalpy of vaporization,$R$ is the gas constant,and $C$ is an integration constant.This equation is in the form of a straight line $y = mx + c$,where $y = \log p$,$x = \frac{1}{T}$,and the slope $m = -\frac{\Delta H_{vap}}{2.303 R}$.Since the slope is negative,the graph of $\log p$ versus $\frac{1}{T}$ is a straight line with a negative slope.
