A given mass of gas expands from state `A` to state `B` by three paths `1,2`, and `3` as shown in the figure below. If `w_(1),w_(2)` and `w_(3)`, respectively, be the work done by the gas along three paths, then
A. `W_(1) gt W_(2) gt W_(3)`
B. `W_(1) lt W_(2) lt W_(3)`
C. `W_(1) = W_(2) = W_(3)`
D. `W_(1) gt W_(2) , W_(1) lt W_(3)`
