Hello Jibendu!
According to cutoffs in past few years, with your current rank, you can easily get Information technology engineering, Electronics and Telecommunications engineering, mechanical engineering, Electrical and electronics engineering, electrical engineering etc. You must note that cutoffs vary too depending upon number of students appearing for the exam, difficulty level of the level, number of seats available etc. So, there is some chance of getting Computer Science engineering too as in 2017, cutoff for Computer Science Engineering was 5044. Hope this answer helps.
All the best!
