A. balance
Cody is using the design principle of balance. Symmetrical patterns of tiny dots that are evenly spaced on the entire garment create a sense of visual equilibrium. This is because the dots are arranged in a way that is equally distributed on both sides of the garment, creating a sense of balance and stability in the design. In symmetrical balance, the elements on one side of the design are mirrored on the other side, creating a harmonious and pleasing effect for the viewer.
