Choose the correct answer:Which statement is true about Boundary Events?

In BPMN (as used in OMG-aligned certifications),Boundary Eventscan be interrupting or non-interrupting. The general rule is:

Many boundary events (Timer, Message, Signal, etc.)can be eitherinterrupting or non-interrupting.

Some types, however, existonly as interrupting boundary events:

Error Boundary Event– always interrupting the activity/subprocess it is attached to.

Cancel Boundary Event– always interrupting and only valid on a Transaction Sub-Process.

Compensation Boundary Event– used to trigger compensation behavior and treated as a special interrupt-style handler attached to the scope of the completed activity.

So, among boundary events,Error, Cancel, and Compensationare treated asalways interrupting variants, in contrast with others that can be non-interrupting.

Thus optionAcorrectly captures this differentiating property; the other options contradict the specification or reverse the visual notation (C) or incorrectly constrain outgoing flows from boundary events (D).
