You have got an excellent rank there of 180 in JEE advanced. With that rank you can easily get any preferred top branch in any of the top IITs. If you go by the general statistics nowadays, Computer science and engineering is the most sought after branch followed by Electronics and Communication Engineering. So apply for these two branches for sure in the top IITS. Apart from this I would like to suggest you to look into your interest too before taking any branch as you will be studying it for four years. Best of luck for future endeavours and do participate in the counselling sessions.
