Hi Rajeev! You can do an MBA from any of the reputed institutes (refer to our B-school cluster guide). There is no area specialisation in M&A at most of the schools but the best course of action for you would be to specialise in Marketing and take up electives (subjects) in M&A and Strategy.

All the best!
