The correct answer is:
Process $A \rightarrow B \rightarrow C \rightarrow D \rightarrow A$ is clockwise.
During $A \rightarrow B$, pressure is constant and $B \rightarrow C$, process follows $p \propto \frac{1}{V}$ ie., $T$ is constant. During process $C \rightarrow D$, both $p$ and $V$ changes and process $D \rightarrow A$ follows $p \propto \frac{1}{V}$ i.e., $T$ is constant.
Hence, equivalent cyclic process is has follows.
During $A \rightarrow B$, pressure is constant and $B \rightarrow C$, process follows $p \propto \frac{1}{V}$ ie., $T$ is constant. During process $C \rightarrow D$, both $p$ and $V$ changes and process $D \rightarrow A$ follows $p \propto \frac{1}{V}$ i.e., $T$ is constant.
