Which principle is associated with grouping changes that happen for the same reasons?

• A. Common Closure Principle
• B. Dependency Inversion Principle
• C. Interface Segregation Principle
• D. Open/Closed Principle

Answer: (A)

Grouping changes that happen for the same reasons is handled by the Common Closure Principle. This principle says that parts of a system that are likely to change for the same reasons should be designed together in the same module, class, or package. By organizing in this way, when a requirement changes and those parts need to adapt, you make the change in a single place rather than scattering modifications across unrelated code. It reduces ripple effects and makes maintenance easier. The other principles address different ideas. The Open/Closed Principle is about designing entities so you can extend behavior without modifying existing code. Dependency Inversion focuses on depending on abstractions rather than concretions to reduce coupling, and Interface Segregation emphasizes keeping interfaces small and client-specific rather than one large interface.
