Could someone please explain the reasoning behind the correct answer for part C?

It would be different because the equilibrium constant is equal to (PO2)^3/(PO3)^2 , not PO2/PO3. The statement in part C doesn't take into account the coefficients of the reaction.

C would have different values for PO2/PO3 for the two samples since only the equilibrium constant, which would be PO2^3/PO3^2, would have the same value between the two samples as it is a constant. It's kind of like a trick question to see if you can recognize that PO2/PO3 is not the equilibrium constant and thus would be different for the two samples.
