This is the use of change in writing and design often enough to stir reader's interest and direct attention.

• A. Rhythm
• B. Variation
• C. Movement
• D. Contrast

Answer: (D)

Contrast is the main idea here. It uses differences to grab interest and direct where the reader looks. In writing, contrast can show through opposing ideas, shifts in tone, or varied sentence lengths, all of which highlight important points. In design, contrast comes from differences in color, light and dark, size, weight, or typography, making key elements stand out. This deliberate difference helps create a focal point and guides the reader’s eye through the text or layout. While rhythm, movement, and variation can add interest, contrast most clearly and reliably directs attention by making certain parts visibly different from their surroundings.
