Confusing question in FlexBox quiz

Isn’t this question a bit confusing? As align-items aligns items along the cross-axis, which not necessarilly is vertically…

Or have I misunderstood something?

It seems you have a good understanding here.

Maybe the wording of the question should have specified “with a default flex-direction” to make it clearer. The default is row and would eliminate the horizontal options.
