From the graph, area under path $A$ is the largest whereas under path $c$ is the smallest.

Thus $W_{A}>W_{B}>W_{C}>W_{D}$            $...(1)$

From Ist law of thermodynamics, $Q=\Delta U+W$       $...(2)$

As $\Delta U$ is a state function, thus $\Delta U$ is same for all paths.

From $(1)$ $\&(2), \quad Q_{A}>Q_{B}>Q_{C}>Q_{D}$

Also for path $\mathrm{A}$ and $\mathrm{D}, Q_{A}=\Delta U+W_{A}$ and $Q_{D}=\Delta U+W_{D}$

subtracting these two, $\Longrightarrow Q_{A}-Q_{D}=W_{A}-W_{D}$

Similarly, $Q_{B}-W_{B}=Q_{C}-W_{C}$
