From ideal gas equation,

\begin{aligned} \mathrm{P V =n R T} \\ \end{aligned}

\begin{aligned} \mathrm{\Rightarrow P =\frac{d R T}{M_{0}}} \\ \end{aligned}

\begin{aligned} \mathrm{\Rightarrow P =\left(\frac{R T}{M_{0}}\right) d} \end{aligned}

\therefore P vs d will be a straight line passing through origin.

Also, \mathrm{Slope \propto \text{T}}

So, greater the temperature, greater is the slope of the plot.

Hence, the answer is Option (2)
