Central Board Of Secondary Education [CBSE] — I'm complaining about the fault of CBSE on geography class 12 Exam[protected]

I want to complaint about CBSE 12 geography exam Q.53 to Q.56. It was a graph based question in which graph was not correct. I and many of my friends know that it was not correct but we thought that we should answer the questions according to the graph presented to us only. So we did the same but according to official answer key our answers were not correct. It is unfair for us . So my humble request to you is to please look into this matter so that we can also get a fair chance .

Thank you
