Entropy is the extensive property and Molar entropy is an intensive property.

Actually, in a way, entropy is all three.

First, entropy depends on the mass of the body or extensiveness of The body and thus, is an extensive property. But specific entropy is intensive.

Now, entropy is a state function for sure. It depends on the endpoints of the process only and doesn't depend on the path. This is because entropy is the degree of randomness which irrespective of the path should have specific end values.

Now, it's a Macroscopic property since we consider it for massive bodies. This is because the randomness of a few molecules is difficult to quantify.

So, Answer D is correct.

Entropy is a intensive and state function because it is not depend on start and end.

Entropy is an intensive property and it is a state function.

So, the right answer is Option A.

Both option A & C is the correct answer.

Yes, I too agree, Both A and C options are correct.

Entropy state and extensive property because more mass will be more disorder and it depends on the initial and final state of the system.

Entropy is a state and extensive property.
