What math is best for college admission?

I’m still puzzling about how you can get an art credit for a business class!

For IB, in lieu of a Group 6 (Arts) course, you can take a second course from Groups 1-4, but a college-level business class does not count for IB. But I’m not understanding the original question, as one needs a Group 5 math class for the IBDP.
