Solution
The correct option is A Adiabatic The P−V diagram of adiabatic process, isothermal process and isobaric process are shown in (figure).
Work done in process= area enclosed by P−V diagram with volume axis.
Since area under the curve is maximum for adiabatic process, so work done on the gas will be maximum for adiabatic process.
