In the reported figure, there is a cyclic process A B C D A on a sample of \(1 \mathrm{~mol}\) of a diatomic gas. The temperature of the gas during the process \(A \rightarrow B\) and \(C \rightarrow D\) are \(T\), and \(T_2\left(T_1>T_2\right)\) respectively.Choose the correct option out of the following for work done if processes BC and DA are adiabatic.
