If you focus solely on the branch then electrical will win and you have your answer but if you look in overall prospective then you will notice that iit roorkee has better brand value than ism dhanbad so the decision remains between i&p and civil where in terms of placements civil might win but i&p is a branch related to mechanical engineering and its applicability in future cannot be counted out. So at the end you have to choose but overall iitr civil or i&p both are good choices.
