Explanation

An Event-based Gateway pauses process flow and waits for one of several possible events to occur, then immediately routes execution down whichever path corresponds to the event that fired first - making real-time responsiveness its defining characteristic (C). Option A describes a joining/synchronizing gateway (like a parallel gateway), not an event-based one. Option B sounds like a merging gateway that combines event flows, but an event-based gateway branches on alternative events, not combines them. Option D is a side effect that might occur in some designs, but it's not the purpose or benefit of this gateway type.

Memory tip: Think of the Event-based Gateway as a "whoever calls first wins" mechanism - the process sits idle at the gateway and the first event to arrive (a message, timer, signal, etc.) immediately determines which path is taken.
