If your friend tell you that hope you get back your brain from the hospital which u left 12 years ago soon what could you reply back? can plz one help me now??

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.
