This lesson is about plural objects/plural accusatives. Where is the object here.
You also need to recognize when you do not use an accusative. This is one of those times.
I think this specific question is only for plural
They are "women", "girls" or "ladies" also count.
The whole point is they NOT women (or ladies) - they are girls. That is, young (pre-pubescent by some definitions) female humans.
Women would be "nők"
'Ladies' would be 'hölgyek'.
