M.Tech

Dear Chirag Patel,
All are good and fine. It depends on your interest. M.Tech, ME and MS leads you to stick your own core area, where as MBA, leads to executive life in the area of marketing, operations and production management, etc. Therefore, if you want to stick your core go for M.Tech, ME, etc. if not MBA.
All the best.
