Which complementary colors did the artist use in this painting? a. green and yellow b. red and green c. yellow and orange d. red and orange

i think it is d but idk

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.
