Which of the following is one of the six integral design components?

• A. Line
• B. Rhythm
• C. Proportion
• D. Balance

Answer: (A)

In design, there are building blocks called elements and then principles that describe how those blocks are used. The six integral design components are line, shape, form, space, texture, and color. A line is one of these elements because it defines edges, directions, and boundaries in a composition; it’s the basic tool for organizing space and guiding the viewer’s eye. The other terms are principles, not elements: rhythm describes repeating patterns that create movement, proportion is about the size relationships between parts, and balance concerns how visual weight is distributed. So line is the correct choice because it’s an elemental component used to build and define design, whereas rhythm, proportion, and balance are principles that arise from arranging those elements.
