What is the notation of a transition in a state machine diagram?

• A. A solid line with an open arrowhead from a source to a target
• B. A dashed line with a filled arrowhead
• C. A curved line
• D. A dotted line

Answer: (A)

In a state machine diagram, a transition is the directed move from one state to another in response to an event. This is shown as a solid line with a hollow (open) arrowhead pointing from the source state to the destination state. The solid line communicates a direct state change, and the arrowhead indicates the direction of the change. Other line styles, like dashed, dotted, or curved lines, are used for different relationships or annotations and are not the standard notation for transitions.
