It would be pretty flat (and not much of a pyramid) at the extreme values, but I'm pretty sure that answer C is your winner.  The other answers don't allow the side to be a triangle, since they put together combinations of sides that don't meet the requirement that the longest side is shorter than the sum of the other two.
