Which type of design uses shapes like lines, circles, and squares?

The correct choice is geometric design, as this type of design is characterized by the use of simple, clean shapes such as lines, circles, and squares. Geometric design focuses on the arrangement of these fundamental forms to create compositions that are often more structured and mathematically precise. This style is prevalent in various areas, including architecture, graphic design, and textile patterns, where the emphasis is placed on symmetry, proportion, and patterns formed by the arrangement of geometric shapes.

Other design types, such as naturalistic, stylized, and abstract designs, may incorporate shapes or patterns but do so in different ways. Naturalistic design draws inspiration from nature, emphasizing organic forms and lifelike representations. Stylized design simplifies or exaggerates forms while maintaining some elements of their original character, often for aesthetic appeal. Abstract design focuses on using shapes, colors, and forms not directly depicting the real world, often emphasizing emotion or concept over recognizable figures. In contrast, geometric design's specificity and focus on basic shapes and their relationships make it distinctly identifiable among these options.
