Both carer options are equally good with multiple opportunities, you are advised to choose any based on your interests to excel in career.

First, work at least 2 years on your graduation. After that, think of any course.

The eligibility for PGDM and MBA is Bachelors degree in any discipline from a recognized university with aggregate marks of 50% or above. As you are already a graduate, you are eligible for PGDM if your marks are above 50% in graduation degree.
