A given mass of gas expands reversibly from the state \( A \) to the state \( B \) by three paths 1,2 and 3 as shown in the figure. If \( w_{1}, w_{2} \) and \( w_{3} \) respectively be the work done by the gas along three paths then:
(a) \( w_{1}w_{2}w_{3} \)
(b) \( w_{1}w_{2}w_{3} \)
(c) \( w_{1}=w_{2}=w_{3} \)
(d) \( w_{2}w_{3}w_{1} \)
