(B) In the given $p-V$ diagram:$1$. Process $AB$: Pressure $p$ is constant,so it is an isobaric process.$2$. Process $BC$: It is given as an isothermal process ($T$ is constant).$3$. Process $CD$: Volume $V$ is constant,so it is an isochoric process.$4$. Process $DA$: It is given as an isothermal process ($T$ is constant).Now,let's analyze the options:- For option $(A)$ ($p-T$ diagram): $AB$ is shown as isochoric ($V$ constant),which contradicts the $p-V$ diagram where $AB$ is isobaric. Thus,$(A)$ is incorrect.- For option $(B)$ ($V-T$ diagram): $AB$ is shown as isobaric ($p$ constant),$BC$ is isothermal ($T$ constant),$CD$ is isobaric ($p$ constant),and $DA$ is isothermal ($T$ constant). This matches the characteristics of the $p-V$ diagram.Therefore,the correct representation is $(B)$.

Column $I$	Column $II$
$(A)$ An insulated container has two chambers separated by a valve. Chamber $I$ contains an ideal gas and Chamber $II$ has a vacuum. The valve is opened.	$(p)$ The temperature of the gas decreases
$(B)$ An ideal monoatomic gas expands to twice its original volume such that its pressure $P \propto V^{-2}$	$(q)$ The temperature of the gas increases or remains constant
$(C)$ An ideal monoatomic gas expands to twice its original volume such that its pressure $P \propto V^{-4/3}$	$(r)$ The gas loses heat
$(D)$ An ideal monoatomic gas expands such that its pressure $P$ and volume $V$ follow the behavior shown in the graph	$(s)$ The gas gains heat
