Dear student,

There is nothing like best optional subject in UPSC CSE. One optional can be best for one person but bad for another. You should choose your optional solely on the basis of your area of interest and nothing else. If you enjoy studying your optional, then thay will really fetch you good marks, no matter what is pass percentage of that subject in the past.

So, choose according to your interest. If you are not able to find your interest, shortlist 3 to 4 subjects in which you thing you can be comfortable and then read some ncerts and books related to the same and also don't forget to analyse PYQ of the same and then you'll get to know which subject you enjoy reading and choose accordingly.

Thank you!
