B)​Package diagram and CRC cards
C)Sequence diagram and communication diagram
D)​Sequence diagram and design class diagram

Quizplus · Accepted Answer

The primary models in object-oriented detailed design are the sequence diagram and the design class diagram. The sequence diagram shows the interactions between objects in a particular use case or scenario, while the design class diagram shows the classes and their relationships in the system. Together, these two models provide a comprehensive view of the system's behavior and structure. Therefore, option D is correct. Option A is incorrect because a component diagram is not a primary model in detailed design, though it is used in system design. Option B is also incorrect because CRC cards are not a model in themselves, but rather a method for creating models. Option C is incorrect because the sequence diagram is a primary model, but the communication diagram is not commonly used in detailed design.
