Please see the attachment for my question

Dear Sumukath M lohit,

              The answer in above image is B.P₁₂ .Because pressure is inversely proportional to the volume.And P₁ is very rapidly decreases then P₂ it shows P₁ is very low than P₂.

No the answer key says (c) . even I had got the answer as (b) but I went wrong.

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 V₂ > V₁ and 

so order for pressure will be reverse therefore the answer is P₁ > P₂
