The techniques best suited to illustrate the interaction of runtime building blocks are:A. Activity diagrams - Useful for showing the flow of control among various activities and decisions in the system.B. Sequence diagrams - Ideal for depicting the order of messages exchanged between components or objects in a specific scenario.C. State diagram - Shows how a component or an object changes its state in response to events, highlighting dynamic behavior.G. Depiction of screen flows (sequence of user interactions) - Useful for visualizing the sequence of user interactions with the system, which is critical for user-centric design and runtime behavior analysis.

The correct statements about design patterns are:A. Design patterns are not invented but discovered. - Design patterns represent solutions to common design problems and are derived from repeated experiences and observations in software development rather than being invented.B. Design patterns should always be described alongside the problem they are supposed to solve. - A fundamental aspect of using design patterns is understanding the specific problem a pattern addresses, which helps in applying the pattern effectively in relevant scenarios.

Designing effective interfaces is critical in software architecture, ensuring that they are both usable and robust. The characteristics that generally make interfaces more desirable include:

• A: Easy to extend - An interface should be designed such that it can be extended without breaking existing implementations. This characteristic is important for maintaining backward compatibility while allowing for future growth and changes in requirements.
• C: Clear descriptions of assertions and prerequisites - Interfaces should clearly specify what is required of the caller (prerequisites) and what the interface guarantees in return (assertions). This clarity is vital for ensuring that the interface is used correctly.
• G: Hard to misuse - An interface should be designed in such a way that there is little room for incorrect usage by the client. This involves making the interface intuitive and minimizing the potential for errors, which improves the robustness and reliability of the software system.

These characteristics help in creating interfaces that are not only functional but also robust, maintainable, and adaptable to future needs, aligning with best practices in software architecture.
