When do we need to draw Activity Diagram when developing Use Cases?

  1. Describe sequence of activities for both conditional and parallel behavior.

  2. Describe behavior of an object across several use cases

  3. Used to show behavior of several objects within a use case

  4. Describe relationships between classes and constraints.

A Correct answer
Explanation

Activity diagrams model the flow of activities within a use case, showing sequential, conditional (branching), and parallel (concurrent) behavior. They visualize the workflow from start to finish, including decision points and concurrent activities. State diagrams track object lifecycle across states, sequence diagrams show object interactions, and class diagrams show static structure.
