It is the special fact of isothermal.

I think that isentropic process will result maximum work for expansion process.

An isentropic process implies an adiabatic and reversible process. Reversible work will produce your highest yield of available work so the answer is C.

Here, 1 point. Expanding of gas means volume is not const. The pressure is given, so we have a relation P inversely proportional to V. Pressure decreases therefore in this case temp didn't came into the picture because it is considered as constant variable. So the process is ISOTHERMAL.

Here in this process temperature and pressure changes with respect to time. So process is isothermal.

Both adiabatic and isentropic are the same process then the alternate is isothermal.

Temperature is constant pressure is vary inversely proportional to volume.

Adiabatic lines on a PV diagram are always steeper than isothermal lines. This means that if we change the pressure by a specific amount the change is volume is always going to be more for an isothermal process then an adiabatic process.

Boyle's law proves the answer is (A) ISOTHERMAL. For pressure to increase significantly and bringing about maximum work then absolute temperature must be held constant.
Under this Isothermal process we have Maximum Work Reversible,
i.e Wr = P1V1*ln (P2/P1).

i.e Wr = P1V1*ln (P2/P1).

Consider a system possessing a piston-cylinder arrangement. Now are asked that; which process requires maximum heat (Q) to raise the piston.
So it is clear that if the piston-cylinder arrangement is considered as isothermal; then I have to provide maximum heat (Q) to the system. So the answer is (A).
