Which option should you use?

You add a business process flow to the Account table. The flow has three stages.

You need to ensure that a workflow can run when a user completes the final stage.

Which option should you use?
A . Start when: Record status changes
B. Available to run: Run this workflow in the background
C. Available to run: As an on-demand process
D. Available to run: As a child process

Answer: C

Explanation:

You can trigger on-demand workflows from inside a business process flow. For example, you can add an on-demand workflow to a business process flow so that an activity, such as a task or email, is created whenever a stage is completed.

Note: A workflow becomes activated based on where you drop the workflow onto the business process flow designer.

On-demand stage processes. When the workflow is dropped onto a business process flow stage, the workflow is triggered on entry or exit of the stage.
