Who knows which graphic reasoning to choose?

Look at the first picture first, the first one is two strokes, the second one is three strokes, and the fourth one is four strokes, so the question mark must represent four strokes, excluding A. Then look at the third picture in the first picture, which is composed of the first two pictures, which means that the picture represented by the question mark must be composed of the first two pictures. Rotate the second picture and disassemble the top corner, which is the D option of the first picture group.
