The Correct answer is C.
In other words, for the expansion or compression of a perfect gas at constant pressure, n=0. When n=1, then PV = Constant, i.e. the expansion or compression is iso-thermal or hyperbolic. When n lies between 1 and n, the expansion or compression is polytropic, i.e. PVn = Constant.

The correct answer is C.
Because, in the adiabatic process no heat is transferred, but in the polytropic process some heat is transferred.

The correct answer is c.
Because polytropic process defines all the process like for n=0 isobaric n varies from 0 to 1.4.

Yes, I agree with you @Rishabh.
And also, it is not mandatory that expansion or compression takes place through the law pv^n only.

Why not D? Because compression and expansion take place adiabatically.
