as part of their third-year defence against the dark arts exam, what creature did harry’s class have to navigate when crossing a series of potholes?

i would say the answer is b. zigzag lines of the leaves. i believe this is the answer because zigzag lines go in different direction while the other options like: the vertical lines of the trees, the dotted lines on the road, and the curved lines of the park benches go in one direction.

the previous answer given.
