Solution

The correct option is A $V_{1} < V_{2}, V_{3} < V_{4}$ and $V_{2} > V_{3}$
For idea gas $P V = n R T$
According to graph $P V =$ Constant
In graph, at point 1 pressure is greater than point 2 and we know $P V =$ constant, so at point 2 volume is greater than point 1.
We can check other point also like this.
