I am Sorry guys, but this thing happen every year where people bring lots of sources to argue what is right and wrong. It is all subjective and it is in upsc basket to decide which interpretation will be right or wrong. You all should study or do something else which will be productive rather than arguing on the forum to get some mental satisfaction since no one can be 100 percent sure about anything in this paper for some questions.
Just my view, please anybody do not take it personally.
