sir, what happens when there is wrong question or wrong option is given in jee advance will they award marks for all or the candidates who attempted it?
Marks is generally awarded to everyone, irrespective of whether or not they have attempted the question.
In case of a potential wrong question, the candidate might have skipped the question, or chose an option close to his/her answer, or just clicked on some random option, but NTA is unaware of what they were thinking. This is why, to avoid any kind of confusion, they give free marks to candidates for that particular question.
I hope that was helpful.
