Hello Sir,
If you are looking for scope in jobs after engineering, then its definitely Mechanical and E&E as compared to Architecture. If I have to rank these streams based on job opportunities, then it would be like this :
1-Mechanical,
2- E&E,
3-Architecture.
It is very important to get a good college for mechanical, E&E or any stream you are interested to study. Top colleges provides much more opportunities and better placements. You can definitely guide him but let the final decision be his own.
I hope it helps.

It is average though. If you are really interested, you can join.

You will have to fill the form and then check the cut-off list. Official site is www.kuk.ac.in.

You have a high chance of getting biotechnology. Speaking of scope in India, it is limited only to research and one cannot hope to get placements like in CSE/IT. Also, one needs to do Masters in the field to be eligible for research in the field.
