Which element in BPMN represents a decision point that controls branching?

• A. Task
• B. Event
• C. Gateway
• D. Data object

Answer: (C)

In BPMN, a gateway is the element that controls the flow of the process by deciding which path to take next. It serves as the decision point that manages branching, merging, and synchronization of different sequence flows. There are several gateway types, such as Exclusive Gateway (one path chosen based on a condition), Parallel Gateway (splits into multiple concurrent paths), and Inclusive Gateway (one or more paths may be taken), among others. The key idea is that gateways determine how the process splits and converges, rather than performing work or representing data.

A task represents work to be done, an event is something that happens, and a data object contains information used or produced by the process. None of these control the branching of the process flow, which is why the gateway is the correct choice for a decision point that directs which path the process will take.
