How do you answer which specialization you want to go into (in an MBA interview) if I have not decided yet?

You can just politely say “I am yet to make a choice basis my understanding, potential and interest on the subject line. I understand that initial first year I will be studying all the subjects and during my initial learning stages, I will be able to figure out what is that I would like to pursue in final year of MBA"
