What is the fingerings for a c sharp on the clarinet

Thumb 1 2 3 and the key closest to the bottom upper key

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.
