Dont look for scope , do what you are interested in.
Mechanical,Civil,Production and Metallurgy have a lot of laboratory and Drawing sessions.
EEE ,ECE and ICE deals with circuits and related stuff.
Try googling about the different branches and pick what you like .

HI, In engineering the top branches are:
1. CSE
2. IT
3. Mechanical engineering
4.EEE
5. ECE
6. Civil
7. Aeronautical

These are some of the branches you can opt for as per your interest as well.

The cutoff is generally high for top most branches and therefore while preparing keep you targets and aim high.

Good Luck.
