Bhai use better pattern to write the program........this one will hurt to understand and debug after sometime.

The fact is using json hurts.... this will become a problem .... try using arrays or multi-dimensional arrays for the program..... when you will input a number of questions in json the parsing time will incre3ase time and space complexity of the program and at the time of code review this might make a good impression but in practice it is really crappy try using dictonaries lol..
