Which of the following is considered an element of design?

Balance is considered an essential element of design because it refers to the visual stability and equilibrium within a composition. In design, achieving balance involves distributing elements throughout the layout in a way that feels harmonious and aesthetically pleasing. This can be through symmetrical or asymmetrical arrangements that lead the viewer's eye across the design effectively.

Elements of design, such as balance, contribute significantly to how a design is perceived, impacting its functionality and appeal. It embodies the principles that create a cohesive and visually interesting piece, essential for various fields including graphic design, architecture, product design, and more.

Cost, marketability, and branding, while important considerations in the design process, are typically categorized as aspects of design strategy and business considerations rather than core elements of design itself. These factors influence decisions made during the design process but do not define the visual or structural components of a design like balance does.
