Isothermally is right answer.
Because at a constant temperature, expansion occurs and internal energy is zero. So all heat is converted to work.

Yes, you are right @Max.
The area under the curve for an expansion process is the largest for an isobaric expansion in a PV diagram. So, C is correct.

@Ritik.
We know that the area under the curve of a PV diagram is the work.
An isobaric expansion process on the PV diagram will appear as a horizontal line and have a larger area than either isothermal or adiabatic expansion, which slopes downward (if you can't visualize what I'm trying to say, take the PV diagram of a Carnot cycle).

Isothermal is the right Answer because in the PV diagram Area under the curve for Isothermal is more than that of the adiabatic process.

I agree with you, Thanks @ Flowi.

The Isobaric, isothermal and adiabatic processes are represented in P&V as the following.
Since, the area under the P/V plot for isobaric process is more than the isothermal and adiabatic process the work done in isobaric process is highest.

Isothermally is the correct answer.

Isothermal is the right answer because of the internal energy change caused by work done only.
