Cost-related constraints are rules that limit how much money you can spend on a project. In a design project, the total material and production cost must stay under a given budget, so you have to make choices that keep costs down while still meeting user needs. This drives trade-offs like selecting cheaper materials, simplifying parts to reduce manufacturing steps, or altering features to lower tooling and labor costs. The other options describe constraints related to branding, sustainability, or performance testing, which are not about cost limits. The budget cap is the clear example of a cost-related restriction and it shapes decisions throughout the design process.
