yes answer should be ( c ). for solving these typ of questions, firstly you should draw a line parallel to y-axis. let that drawn line intersect line P1 at point A and P2 at point B. Now compare the volumes for point A and B. At point A let volume be V1 and for point B let it be V2. then you will conclude that V> V1 and P\propto \frac{1}{V}
so order for pressure will be reverse therefore the answer is P1 > P2
