Solution:

$A B \rightarrow$ Constant $P$, increasing $V$, increasing $T$
$B C \rightarrow$ Decreasing $P$, increasing $V$, constant $T$
$C D \rightarrow$ decreasing $P$, Constant $V$, decreasing $T$
$D A \rightarrow$ increasing $P$, decreasing $V$, Constant $T$
Also $B C$ is at higher temperature than $A D$ hence graph $C$ is correct curve.
