Which of the following would NOT be associated with modern design?

The correct answer is based on the fact that modern design is closely tied to specific aesthetic principles and historical contexts that emerged in the early to mid-20th century. Although products designed since 1900 could be part of modern design, not all products from that time onward necessarily adhere to the principles of modernism.

Modern design emphasizes characteristics such as clean lines, minimalism, and functionalism, which are more defined by the specific movements and architectural philosophy that developed in the early 20th century. This movement sought to break away from ornamentation and historical styles, promoting the idea that the design of objects should be directly connected to their purpose and practicality.

In contrast, options discussing clean lines, specific key architects associated with modernism, and the form-function relationship are all integral aspects of modern design philosophy. Thus, claiming that any product designed since 1900 falls under modern design disregards the specific attributes and intents that define it.
