What are the parameters of a sample of gas that are all interrelated and affect each other when any one of them changes?
A. Pressure, volume, number of moles, and temperature
B. Shape, hardness, transparency, and odor
C. Mass, density, color, volume, and pressure
D. Temperature, pressure, number of moles, and molar mass
I am pretty sure that the answer is either A or D.

Well, you know it can't be D. Molar mass doesn't depend on T, P, or number of mols does it?
I repeat, it can't be D. Molar mass doesn't change when pressure or temperature changes.
So is the answer A.
My take on this is as follows.
B. Does changing shape, hardness, or transparency change odor? I don't think so. So I rule out B.
C. Does change P change mass? no. Does changing mass change density? no. So I rule out C.
D is already ruled out because we know changing pressure or temperature of number of mols has no effect on the molar mass. We get that by adding up all of the atomic masses. So D is gone. That leaves only A.

A is correct if you're taking Ape courses
