Literature is a wonderful subject. It's a facilitating A Level, meaning that universities really love it, especially if you maybe go on to do something English/humanities based at university!
Biased because I do it, but I really enjoy it. Great if you love reading, but as for the essay writing skills, those are something you will come to develop, trust me.
Business is classed as a softer subject. Universities aren't that bothered, and if that's not something that you care about then it's no problem! The only reason I bother to consider these things is because if you're still not certain about what you wanna do at university, it keeps your options open.
You don't necessarily need business A Level to do it at university, but you would need literature at a level to do a literature degree.
The bottom line is, do what you prefer. If you think you'd like business more then go for that, but if you're totally stuck, I'd say go for lit as it will keep your options open.
