Entropy is a function of all available options.
So, D is the correct answer.
So, D is the correct answer.

I also agree with you @Vivek.

Work is high grade energy so entropy can not be expresse as function of work,
Entropy express as function of T&P, T&V, and heat.
So correct answer is A&B.
Entropy express as function of T&P, T&V, and heat.
So correct answer is A&B.

Answer is A & B correct @Om Nagar.

That is a change in entropy. Absolute entropy has a different formula only dependent on p and t @Vivek.

Entropy is a function of temperature it is independent of pressure and volume.
Then how? pressure is given.
Then how? pressure is given.

Entropy is a point function which is a property of the system, thus it can be expressed in the form of other point functions, which is also obvious from tds relations. Next, like internal energy which is a point function but can be expressed as function of heat and work (Ist law) so does entropy so correct option is D.

Entropy being an extensive property depends only on temperature and pressure which are also extensive properties if it is function of volume it would not be a extensive property as volume itself is not extensive.
