IS D CORRECT ANSWER?THANK YOU:))))
I couldn't find a copy of this scale, but I believe D is correct.
I agree, by 36 months they do not have difficultly with steps, unless carrying something, like a beach ball. or a large doll.
Not familiar with that one either, but by process of elimination, I would say D also.
