You can choose any of the above according to your interest.  From monetary salary point of view MBA is a better option. And,  if you have good academics and are able to crack CAT,  you can make it to top IIMs also. There is a weightage for variety and you BA can get you additional marks in admission processes of MBA colleges. MBA salary typically starts from 6-7 lpa from a decent college. Dietician fetches you starting salary from about 2.5lpa. Also MBA can give you access to leadership roles in organizations and if you think being a good manager is your calling,  don't think about it and start your CAT prep. But let me also warn you that MBA admission has fierce competition and it is very difficult to get good colleges.
