Final answer:
Postmodernism in architecture involves the combination of c) eclectic design elements, incorporating styles or ornaments from the past onto new buildings.
Step-by-step explanation:
Postmodernism in architecture includes the combination of eclectic design elements. Postmodern architects reject the stark lines of the International Style and instead incorporate or appropriate styles or ornaments from the past onto new buildings. This approach allows for playful colors, forms, and ornaments that reference disparate historical eras, resulting in a more eclectic and diverse architectural style.
The goal of post-modern architecture is to combine various components, forms, and materials to create compositions that are distinctive and visually arresting. This can entail contrasting various architectural styles, combining whimsical and fun features into the design, or combining classic and contemporary components.
