Hello,

Both the courses you have mentioned hold much significance in UPSC syllabus that of general studies or optional subject, so it's a question of which subject you find more interesting, and wish to pursue ahead, with economics there is exam held by upsc as well for recruitment of candidate belonging to this domain, so apart from UPSC, there is much scope in india economics exam if in future you do master's degree, and there are opportunities in banking/insurance companies as well more aligned with your academic study, the relevance of political science too have widened more so in recent times, you can work as researcher, faculty, think tank, various organizations etc, so this field too have much prominence, however it depends entirely on your areas of interest, and in case you want to have back up plan with UPSC or not.
