As we learnt in 

Work by area -

If we plot a process on PV diagram.Then area under the curve will give work done.

- wherein

 

 

All the process are shown in the given figure.

\\ ia\rightarrow Isobaric \\ \\ ib\rightarrow Isothermal \\ \\ ic\rightarrow Adiabatic

Work done is area under PV diagram

Maximum area covered under ic - Hence maximum work done during adiabetic process.

Correct option is 4.


Option 1)

Isobaric

This option is incorrect

Option 2)

Isochoric

This option is incorrect

Option 3)

Isothermal

This option is incorrect

Option 4)
