You asked the question rightly. It is a matter of center of gravity. A down and dirty ay to thnk of that is as the point where, if youwere to be able to hang the tractor from two points or more, it's the place where the vertical lines from the suspension points would intersect.
Rollovers happen when that point falls outside the footprint, with the nuances that JimN described.
Comparing a B to a C . . . If you think about it the front ends are very nearly the same. (Narrow fronts of each have the same bolster, so height isn't all that different.) But a C can be set up much narrower than a B or even 6" narrower than a BN. Allow that the different style tranny puts weight higher than the Bs, and the fact that the operator's weight is also perched atop that instead of adding weight lower and to one side like on the B, the center of gravity is higher and therefore doesn't have to to tip so far before the COG will cross that imaginary line beyond which it will roll.
Nature of the beast, and just one more argument for the need to use one's head. If it don't feel right, stop and get out of there the way you came.
