I do not think that's where entropy can be expressed as a function of pressure, temperature and volume.

Entropy is a function pressure and temperature, volume and temperature, pressure and volume. Also, Entropy = Heat supplied/temperature. So, the correct answer is option (D) all of these.

I agree with you @Vivek.
Because the three equations of TDS came out from expressing entropy as fun of p & v, p & t and t & v.

I agree with the Vivek statement.

I Bilieve that a and b answer is correct.
Because from two property rule, any property can be expressed as the function of any other two property.
Heat and work are path function and not property of the system.

According to me, answer A and B both are correct. Answer C is not because entropy change is associate with flow of heat only not with flow of work.

Tds = U+pdV.
Q = T * dS.
UnAvailable energy = f(W) = f(S) where f means function.
It can be expressed in both volume and pressure as well as temperature.
