What is the most useless branch at NIT, Rourkela?

I don't think there is a single useless branch at NIT Rourkela or at any institute. The diverse branches aim at catering to the needs of all kinds of students. So a branch that is useless for you might be useful for someone else and vice versa. Moreover, if a branch seems to be useless then it's because its students are not passionate enough to make the most out of it. Comparing branches can also result in this preconceived notion of a rank being inferior to the other. 

It's always better to find solutions than to complain. Rather than declaring a specific branch to be useless, we should identify its weaknesses and work on them for instance, one of my friends found his branch to be below average and he along with his batchmates used to sit and single out companies that could hire them they even talked to the professors regarding the changes that coil be made in the curriculum to make the course more appealing and informative.

I believe once you start focusing on gaining knowledge rather than earning money, you won't find a single branch useless. Yes, a branch can provide lesser job opportunities than other branches but that does not make it useless.
