Final answer:
Good design is the product of both aesthetics and functionality, as these aspects work together to meet practical needs while engaging with popular culture.
Step-by-step explanation:
The dislocation of form and function poses a significant challenge in product design. The answer is c) Both. Good design is often a balance where form and function complement each other. The philosophy of "form follows function" highlights that the shape of a building or object should primarily relate to its intended function or purpose. In the context of product design, this balance allows products to not only meet practical needs but also to engage with aesthetics, thereby becoming a part of popular culture. Therefore, while functionality is central to the effectiveness of a design, aesthetic considerations can enhance the user experience and ensure the product's relevance over time.
