I think Option B is correct.
Closed system composition is constant since no mass is transferred.

The equation is;
dU=TdS−PdV applies to a closed system of constant composition.
This is because the equation represents the first law of thermodynamics in differential form for a closed system where the internal energy changes due to heat transfer and work done by the system.
The assumption of constant composition implies no changes in the number of particles or chemical reactions within the system.
