You create a new business process flow with “None” for the entity. 
What type of business process flow have you created?

Answer options:

A.Automated flow
B.Embedded within model-driven app flow
C.Immediate flow
D.Immersive flow
E.Desktop flow

Correct Answer: D 
Power Automate provides the five types of flows: Automated — this cloud flow type is triggered by an event, like when an email comes from your manager.
Instant — this cloud flow type is triggered manually, like when you push a button.
Schedule — this cloud flow type is triggered on a schedule, like sending a report on every working day at 8 am.
Desktop — this flow type automates processes on your desktop.
Business process flow — this flow type guides users step-by-step through the business process.
Business process flow has two varieties: embedded and immersive. 
The business process flows within a model-driven app are the embedded flows. They are part of the model-driven app solution. 
The stand-alone business process flow that provides a total end-to-end solution is called immersive. 

When you omit an entity selection for the new business process flow and select “None,” the Power Automate creates a new Dataverse table under the name of your business process flow. This table stores information about your flow and data from the flow. 

All other options are incorrect.
