CSE, ECE and IT these branches are considered as best for girls. there are several reasons and considering all you need to choose your stream:

• ECE can get you a core Job and also an job related to IT but with IT you can never get a Core Job. IT is more related to CSE so if you had already decided that you want to pursue CSE then IT is a better option.
• ECE can be considered as better nowadays because it is a combined subject that contains electrical subjects as well as it subject and a very few CSE subjects. Skating job in these three sectors are possible for electronics and communication engineering students. So the job opportunity is is overall better in this dream compared to IT.
• Electronics and Communication Engineering (ECE) is considered evergreen for job opportunities in India. Even during the recession, this field is not likely to affected and continue to produce for jobs. So as Both CSE and ECE are great for girls and girls are outnumbering boys in admission for these courses in colleges of India, so considering Job opportunity ECE would be better choice.

Electronics and communication engineering and Information Technology both are best in its own way. But as Job opportunities in multiple sectors are available so ECE would be a better choice. Though if you get a well established Institute placement should not make that much difference.

Hope it would be helpful.
