One way to show multiple, independent alternative paths within an activity diagram is with a _______.

1) synchronization bar
2) swimlane
3) decision diamond
4) activity oval

Answer 1

The correct answer is option 3) decision diamond. A decision diamond is used in activity diagrams to represent a decision point where the flow of control can take one of several different paths.

Step-by-step explanation:

A decision diamond is used in activity diagrams to represent a decision point where the flow of control can take one of several different paths. It typically has one incoming flow and multiple outgoing flows, each labeled with a condition that determines which path to follow.

For example, in an activity diagram representing a loan approval process, a decision diamond can be used to show different paths based on whether the applicant meets certain criteria or not.
