Final answer:
Justified text represents the design principle of c)alignment, creating balanced and uniform text blocks with aligned edges.
Step-by-step explanation:
If the body of the text is justified, it demonstrates the design principle of alignment. Text alignment is a fundamental principle of design that refers to the way text is positioned and lined up in a column or along a page. By justifying text, we create a clean, organized, and visually satisfying block where both the left and right edges are aligned, resulting in balanced and uniform spacing of words and letters across the width of the text block.
Justified text offers a formal and neat appearance, which can be well-suited for printed media such as newspapers, books, and academic documents. While balance and contrast are other important principles of design, they are not directly related to the process of justifying text. Balance refers to how elements are distributed throughout the composition, leading to a sense of visual stability, while contrast is the difference in visual properties that makes an object distinguishable from other objects and the background.
