Choose the correct answer:A process normally has steps A, B, C, and D.

The requirement:

“If step C is not completed within 3 days of thestart of the process, immediately end the process with a failure notification.”

The clean BPMN way is to place A, B, and C inside aSub-Processand attach aninterrupting Timer Boundary Eventto that Sub-Process:

The timer (3 days) starts when the Sub-Process (and thus step A) begins.

If C is completed in time, the normal flow continues to D.

If the timer fires first, itinterruptsthe Sub-Process and flows to a “Notify failure” task and then to an End Event.

OptionDshows exactly this structure: a Sub-Process containing A–B–C with a timer boundary event labeled “3 days” leading to “Notify failure.” The other options place the timer in positions that either start timing from C only or use gateways incorrectly, so they do not satisfy “3 days from start of the process.”

Therefore,Dis correct.
