For an ideal gas, consider only `P-V` work in going from an initial state `X` to the final state `Z`. The final state `Z` can be reached by either of the two paths shown in the figure. Which of the following choice(s) is (are) correct? [Take `DeltaS` as change in entropy and `w` as work done]

`DeltaS_(X)to _(z) = DeltaS_(X) to_(Y) + DeltaS_(Y)to _(Z)`

`W_(X)to _(z) = W_(X) to_(Y) + W_(Y)to _(Z)`

`W_(X)to _(z)to_(Z) = W_(X) to_(Y)`

`Delta_(X)to _(Y)to_(Z) = DeltaS_(X) to_(Y)`
