What can be a better option (I have no interest), IIT Delhi biotech or IIT Kanpur civil?

With no specific area of interest, the best option for you is IIT Delhi Biotechnology. Here are a few points to support my opinion 

• Old IITs have the benefit of equal opportunities for all students irrespective of their branch.
• You are eligible for placements in all types of companies including software.
• As a biotechnology student, you get to do internships in various sectors like IT, finance, etc. 
• Exceptionally good grades can fetch you good packages 
• The quality of college life is better ij IIT Delhi than in Kanpur.

IIT Delhi is the dream college of many owing to the excellent brand name and opportunities it offers. Trust me, once you are inside your branch will hardly matter.
