put them in a series of 5 or so arrays- because it is easier to manage and keep track of the variables
Amending my statement, I misinterpreted the question. I agree that in general An is correct, that a class is better. But arrays allow for lend better to immutablilty because I think it is harder to change the size of them and traversal is faster. If you want mutability then a class is great. As a side note, if you have a large class like that, try to break it into smaller classes, it would help with code readability.
