What is the fee structure of MBA for a BC category student?

The fee remains same for all candidates, but in case you belong to any reserved category, then you can avail a scholarship from social welfare department of your area. You can check the below mentioned link for more details: www.quantum.edu.in

The fees structure for all categories is same, but you should check for the scholarship provided by the college which you have selected.

It completely depends on the discretion of the institute. I would suggest you to get in touch with your desired institute to have a clear idea.
