Which engineering branch has great salary prospects?

Basically higher salary offered in management field like MBA and PGDM, etc. as your interest in engineering then IT field is good for you. I mean B.Tech IT or B.Tech CSE and I would also suggest do a management course after B.Tech for assure a higher salary scale.

Firstly, there are many branches, but you select those in which have your own interests in. And, I think for girls pharmacy, nursing, microbiology, agriculture are the best.

It depends upon the company but I think civil and computer engineering will fetch you a good salary.
