Geography, Chemistry, Biology strike me as a very good combination perhaps with Sociology / Psychology if you fancy them.
I think it'll be a lot of work but worth it in the long run as it keeps lots of options open - pharmacy? geology? psychology ? agriculture? medicine? physiotherapy? all good careers.
It's really important you go wherever will allow you to do the right subjects for you. Can't you change schools/ college? With good GCSEs most places will love to have you.
Not sure about business though - could be boring and not very helpful for degrees in any other line.
