In the context of a Use Case Diagram, what does it illustrate?

1. The financial impact of product features

2. The stakeholders involved in the project

3. All in-scope use cases for a solution

4. Potential risks associated with product features

The correct answer is: All in-scope use cases for a solution

A Use Case Diagram is specifically designed to capture and illustrate the interactions between users (referred to as actors) and the system regarding particular functionalities, known as use cases. This visual representation helps to outline all the in-scope use cases for a solution, indicating what the system should accomplish from the end-users' perspective. By focusing on the use cases, the diagram helps stakeholders understand the coverage of functionalities that the system will provide. This allows for better communication around requirements and expectations, ensuring that all necessary interactions are duly noted and accounted for in the development process. While the other choices might touch on aspects relevant to a project, they do not align with the primary purpose of a Use Case Diagram. For instance, assessing financial impacts, identifying stakeholders, or highlighting risks are critical activities in project planning and management, but they fall outside the specific intent of a Use Case Diagram, which is to clarify and document what functions the system should deliver to its users.
