A gas is expanded from volume \[{{V}_{0}}\] to \[2{{V}_{0}}\] under three different processes. Process 1 is isobaric process, process 2 is isothermal and process is adiabatic. Let\[\Delta {{U}_{1}}\], \[\Delta {{U}_{2}}\]and \[\Delta {{U}_{3}}\]be the change in internal energy of the gas is these three processes. Then-  

A) \[\Delta {{U}_{1}}>\Delta {{U}_{2}}>\Delta {{U}_{3}}\]

B) \[\Delta {{U}_{1}}<\Delta {{U}_{2}}<\Delta {{U}_{3}}\]

C) \[\Delta {{U}_{2}}<\Delta {{U}_{1}}<\Delta {{U}_{3}}\]

D) \[\Delta {{U}_{2}}<\Delta {{U}_{3}}<\Delta {{U}_{1}}\]
