If you are choosing between the two based upon which has the lower amount of work load then business has a very low workload and is a very easy subject. It's like one of those subjects where you don't have to actually think critically, you just memorise the syllabus and do past papers and the questions are always sort of similar. Due to that though it's a very boring subject
If you are choosing between the two based upon what is more interesting I would say learning history is probably more interesting, but it probably has more workload than business
