(C) From the given $V-T$ diagram:$1$. In process $AB$,the line passes through the origin,so $V \propto T$. According to the ideal gas equation $PV = nRT$,if $V/T$ is constant,then pressure $P$ must be constant. Thus,process $AB$ is an isobaric process.$2$. In process $BC$,the line is horizontal,meaning volume $V$ is constant. Thus,process $BC$ is an isochoric process.$3$. In process $CA$,the line is vertical,meaning temperature $T$ is constant. Thus,process $CA$ is an isothermal process.Comparing these characteristics with the given options,the $P-V$ diagram that shows an isobaric process $(AB)$,an isochoric process $(BC)$,and an isothermal process $(CA)$ is represented by graph $(c)$.

$A$ cyclic process $ABCA$ is shown in the $V-T$ diagram. The corresponding process on the $P-V$ diagram is:
