B.A

kindly note, minimum requirement is degree in any subject.

Choose something from your own interest, there's nothing like best or worst. When you'll do your MA, then PhD automatically you'll get good posts as a professor or a research scholar

Hi. It actually depends on your area of interest. If you are interested in teaching than you may go for MA and B'ed after that. Clearing CTET will be an added advantage. If you are interested in some competitive exams you can go for a number of them after your graduation. I hope this will suffice. God bless you.

No university offer 5 years integrated BA LLB course by distance learning. Also, LLB obtained by distance learning us approved by Bar Council of India and such graduates can not practice in courts.

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.
