What's the amount of bright and dark in shading?

i remember this

i was off to a good start

can i get brainlest

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.
