Which design quality concerns the strength of relationships within a module?

### Why this is right Cohesion concerns how closely related the responsibilities within a module are. It is a design concept listed separately from coupling. ### The concept Cohesion focuses inside a module, while coupling concerns relationships between modules. Keeping these ideas distinct helps designers reason about how a system is divided and how its parts depend on one another. ### The other options - **B. Coupling**: This concerns dependencies or connections between modules, not relationships within one module. - **C. Deployment**: This is a process framework activity involving delivery into use. - **D. Feasibility**: This concerns whether a proposed project or strategy is viable. ### Terms - **Module**: A distinct component or unit of a software system. - **Cohesion**: The degree to which responsibilities within a module belong together. - **Coupling**: The degree of dependency between modules. ### Remember Cohesion is within; coupling is between.
