Where is Do on B Major scale?

B – C♯ – D♯ – E – F♯ – G♯ – A♯ – B

Do   Re    Mi    Fa   So     La    Ti     Do

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.
