See from the job perspective, the core jobs in any of the fields mentioned above are getting low and low day by day. So if you wish to go for any of the course among this course then go for the Civil Engineering. See Civil Engineering have a need of quite a large number of engineers in the construction industry. So if you go for it, then getting a job can be easier if you have skills. If you don't even get a job, then also you can practice as a Planner in your Municipal Area. So the alternate way of getting settled is there in civil engineering.

Now if you want to go among the Mechanical Engineeirng & Automobile Engineering, I would suggest to go for Mechanical Engineering because its a much bigger field compared to that of Automobile engineering and the sector is quite large. Being an Mechanical Engineer you can work in Aeronautic sector, Mechanical Sector, Automobile sector, Production sector, Chemical sector etc. So if you have to choose, then choose between Mechanical Engineering or Civil Engineering as this are broad field with good scopes (provided you should have to get the industrial skills).
