For what its worth, I've often used a variation of A in Ruby like this:

[[lower, value].max, upper].min

It will obviously not be faster but perhaps easier to understand for some.

Overall I think I'd prefer solution C now. Having said that, an Array#median method would be great in this case:

[min, max, value].median
