The diagram shows two Participants (A and B) connected by adashed line with an open circle at the source and an arrow at the target. In BPMN this is aMessage Flow.
Semantics of a Message Flow: It indicates thatone participant sends a message to another(cross-pool communication).
Mapping options:
A. "Pushes data"describes data association, not a BPMN message flow. B. "Associated with"refers to
BPMNAssociation, which is also dashed, but used between artifacts and flow objects without the open
circle/arrow message notation.
C. "Performed before"would be asequence flow, which is solid, not dashed. D. "A sends a message to
B."exactly describes a Message Flow.
So, the correct interpretation isD.
