Choose the correct answer:Consider the following diagram:Which statement is true about the execution of Action...

In the provided activity diagram, let’s analyze the execution of Action c:

Tokens and Control Flow:

Tokens represent the flow of control within an activity diagram.

Each control flow arrow represents a path along which tokens can move.

Tokens are offered to actions based on the incoming control flows.

Action c:

Action c has two incoming control flows (from Action a and Action b).

Since there are two tokens offered to Action c, it will be executed twice.

Parallel Flow:

The parallel flow from Action a and Action b does not need synchronization because both tokens can independently reach Action c.

The diagram does not violate any synchronization rules for parallel flows.

Therefore, the correct statement is that Action c will get executed two times, as indicated by the presence of two tokens offered to it.

For further understanding, you can refer to UML 2 documentation on activity diagrams, which explains the semantics of tokens, control flows, and execution of actions1. Remember that tokens play a crucial role in determining the execution behavior of actions in parallel flows.
