Just from the name of the degree I'd say Sociology, Gov & Politics and Philosophy.
However, degrees like this where they don't really have a-level requirements really just look for essay based subjects, so your fine with either. Many of these A-levels arent offered nationwide so they will teach you what you need to know regardless if you took the relevant subjects at A-level
Do have a check if they have module information, and you can maybe tailor the courses better to that instead of just to the name.
