Hello Aisha,

Since you have done your post graduation in sociology so according to me you should choose sociology only as a optional subject as you have studied it for such a long time now and you must have covered many aspects of sociology. Indian Administrative Service is also based most on the social problems that people face in day to day life and that is the only reason why many people choose to serve people by becoming IAS.

I hope I was able to clear your query even though if you want any other information regarding the civil services or defence you can ask me in the comment section.

Hope you do well in future and serve our country.
