Thermodynamic processes are indicated in the following diagram.  Match the following  \(\begin{array}{|l|l|} \hline Column\,\,-\,\,1 & Column\,\,-\,\,2 \\ \hline P\,:\,Process\,\,-\,\,I & \,\,A\,\,:\,\,Adiabatic \\ \hline Q\,:\,Process\,\,-\,\,II & \,\,B\,\,:\,\,Isobaric \\ \hline R\,:\,Process\,\,-\,\,III & \,\,C\,\,:\,\,Isochoric \\ \hline S\,:\,Process\,\,-\,\,IV & \,\,D\,\,:\,\,Isothermal \\ \hline \end{array}\)  

1. A \(P \to C,\;\;Q \to A,\;\;\;R \to D,\;\;S \to B\)
2. B \(P \to C,\;\;Q \to D,\;\;\;R \to B,\;\;S \to A\)
3. C \(P \to D,\;\;Q \to B,\;\;\;R \to A,\;\;S \to C\)
4. D \(\;P \to A,\;\;Q \to C,\;\;\;R \to D,\;\;S \to B\)
