What does a loop combined fragment represent?

• A. A single execution of events
• B. A set of event occurrences that could happen multiple times during a single execution
• C. Two or more alternate event paths
• D. Optional events gated by a condition

Answer: (C)

Loop combined fragments express repetition of the interactions inside them within a single overall execution. The essence is iteration: the contained messages can occur multiple times as long as the loop’s guard or condition is satisfied, often with bounds on how many times to repeat. So this fragment represents a set of event occurrences that could happen more than once during one execution. This differs from alternatives that model choosing between separate paths, options that may or may not occur, or parallel paths that happen concurrently. In practice, you might see a loop with a guard like count < 3, indicating the contained interactions repeat up to three times.
