Solution

In $VT$ graph

$ab-process\,\,\,:\,\,\,Isobaric,\,\,temperature\,increases.$

$bc\,process\,:\,Adiabatic\,pressure\,decreases.$

$cd\,process\,:\,Isobaric\,volume\,decreases.$

$da\,process\,:\,Adiabatic,\,pressure\,increases.$

The above processes correctly respresented in $P-V$ diagram $(b)$ .
