I don't think ict is going to be important for law but it's upto you.
History is great!
And if you want to pick amongst biology, religion and business, biology is going to look the most impressive on your application as a third a level. And it's not essay based but universities look at the sciences very favourably for law, so don't worry at all since you will have History which makes up for the essay.
If you want to go to a good Russel group, in that case you might replace ICT for English literature? Or maybe another science like physics or chemistry, or maybe psychology. Or you can do maths as well.
