D Correct answer
Explanation

Fork and Join Nodes in UML activity diagrams explicitly represent concurrent or parallel process flows. A Fork Node splits one incoming flow into multiple concurrent outgoing flows, while a Join Node synchronizes multiple concurrent flows back into a single flow. Decision nodes handle branching based on conditions, not concurrency.
