Best Straight I would Suggest Just Go For BJMC+MBA. As if you do BBA+MBA then it's related to one field of jobs. Just in commerce field.
But if you do BJMC+MBA then you reach in different sectors increases. As You can Pursue you career in Journalism or mass comm. Which is always the best choice as well as in commerce or management field.
So go for BJMC+MBA for a Better Scope.
Best of Luck,
Thanks for raising you concern Rekha,
