Solution

The correct answer is option 2.

Key PointsUML (Unified Modeling Language) diagrams can be categorized into two main types: structural diagrams (which present a static view of the system) and behavioral diagrams (which represent the dynamic aspects).

• Collaboration diagram – Represents interactions between objects or parts in terms of sequenced messages. It is a kind of behavioral diagram.
• Use-Case diagram – Represents the functionality provided by a system in terms of actors, their goals represented as use cases, and any dependencies between those use cases. It is a kind of structural diagram, providing a static view of the system's functionality.
• State chart diagram – Shows how an object changes its state in response to events. It is a type of behavioral diagram.
• Activity diagram – Represents workflows of stepwise activities and actions with support for choice, iteration and concurrency. It is considered a behavioral diagram.

Therefore, the diagram that represents a static view among the options listed is the Use-Case diagram.
