In the reported figure, there is a cyclic process $\displaystyle A B C D A$ on a sample of $\displaystyle 1$ mol of a diatomic gas. The temperature of the gas during the process $\displaystyle \mathrm{A} \rightarrow \mathrm{B}$ and $\displaystyle \mathrm{C} \rightarrow \mathrm{D}$ are $\displaystyle \mathrm{T}_1$ and $\displaystyle \mathrm{T}_2$ $\displaystyle \left(\mathrm{T}_1>\mathrm{T}_2\right)$ respectively. Choose the correct option out of the following for work done if processes BC and DA are adiabatic.
