A suitable product design should prioritize:

A suitable product design prioritizes user-friendly features because these aspects are essential for enhancing the overall user experience. When a product is easy to use, it increases customer satisfaction and can lead to higher adoption rates. User-friendly features can include intuitive interfaces, clear navigation, and accessibility considerations that make the product accessible to a broader audience.

Prioritizing user-friendly design typically results in products that meet the needs and preferences of the users, ultimately leading to increased sales and brand loyalty. Additionally, designs that focus on usability often incorporate feedback from users during the development process, which helps to ensure that the final product aligns closely with user expectations.

In contrast, the other options would likely detract from effective product design. Complex user instructions can frustrate users and make a product less appealing. High production costs without clear benefits to users can render a product economically unviable, and minimal aesthetic consideration can lead to a lack of visual appeal, which may also negatively impact user interest.
