B.A

doing MBA finance or .CA is good option

There are many career options available but I think you should go for your PG in Economics as career prospects for economics graduates are very good both in the public as well as the private sectors. In the government sector, one may try for Indian Economic Services, jobs in Reserve Bank of India, PSUs and other public sector banks. All these jobs have wonderful career options.
Try to get admission in the colleges like DSE Delhi, JNU, BHU, UPES Dehradun etc which are very popular for this Economics courses. Admissions are still running so you need to apply at the earliest. All the best.
