A-level options for social sciences??

I'm picking my a-levels at the moment, and have settled on history, spanish, and maths as a 4th choice. However, I'm trying to pick between geography and religious studies.
For context, I want to go on to uni, most likely to do something in the social sciences, like politics or law, and potentially with a language.
The units my school teaches for RS at a-level are based on philosophy and ethics - it looks very interesting, but I also quite enjoy geography, especially the human side. Would any of these subjects be more advantageous for me? Any thoughts?

First off, as someone in their second year of A levels, wish you all the best with doing 4 A levels, trust me everyone struggles with just doing 3, but if you feel like you're competent then go ahead, but it's really not recommended at all. Second, although this is a personal choice I may add that it's best not to base topics that are of interest to you within a subject as a reason to doing a level as sometimes it's not what is learned. I have friends doing A-level Geography and they all comment on how A-level Geography is almost a repeat of GCSE! They doing the same trip to Stratford and everything! Just some general advice, sorry if it's not helpful enough I do sciences so not really my field! Best wishes on your GCSE!!!!!
