Which principle is shown by the repeated arrangement in a brick wall?

Correct answer: Rhythm

Rhythm in art is produced when visual units are repeated in an organised arrangement. The repeated rows and intervals of bricks create a recurring pattern that guides the eye across the wall, so they demonstrate rhythm. Contrast concerns differences, emphasis creates a focal point, and proportion concerns size relationships among parts. Although a wall may also contain proportion and contrast, the repeated arrangement specifically identifies option B.
