It's not the branch which gets you more salary. Rather it's your interest which will get you farther in life.

Here are some of the branches of MBA in which you can think about pursuing your MBA course-

• MBA in Finance
• MBA in Health (Pharmaceuticals)
• MBA in Consultancy
• MBA in Information Technology
• MBA in Telecommunications
• MBA in Media
• MBA in Services
• MBA in Hospital Management
• MBA in HR
• MBA in Operations
• MBA in International Business 

and there are many more.

It is not about the best branch but if you have specifically no interest in any then you can follow your educational background like if you are from commerce you can choose finance which is the mostly choosen branch, or marketing if you have the convincing power etc.

You can even know the pros and cons of each branch you have interest in and then you can decide which way to go. Some may have intensive work pressure but high salary and others may have good packages but typically much stable jobs that you become stagnant at one point of time.

Choose your interest!

Good luck.
