Hello,
I must firstly admit that you are not confused but a very good student who has set his aim on achieving something. Great. Just do not worry. You can definitely go for MBA after doing your graduation in B.A.

Hi Mohd,
Yes, but you need to check the institute which you want to enrol. For that you should see that the university you want to do MBA is recognised by UGC i.e. University Grants Commission or not. For that you can go to www.ugc.ac.in and go to the section "Inside HE". Also Your university should approved from AIU, i.e. All Indian Universities.
