You need to create a client-side code for interaction with business process flow on a model-driven app’s form. 
Please select Client API objects you can use in your code.

Answer options:

A.formContext.ui.navigation
B.formContext.data.process
C.formContext.data.entity
D.formContext.ui.process
E.formContext.ui.formSelector

Correct Answers: B and D 
The business process flow is one of the Power Automate flow types. It guides users through the process of data operations with one or several Dataverse tables. Business process flow consists of stages. Each stage can be associated with only one Dataverse table, but optionally, you can select related tables in the One-to-Many relationship with the primary stage table. A stage contains one or more steps that represent the table`s fields. 
If you need to interact with the business process flow on a form with client-side code, there are two types of objects that you can use: the Data — formContext.data and UI — formContext.ui. 
The formContext.data object includes formContext.data.process. It provides objects, events, and methods for interaction with the form`s business process flow data. The business process flow triggers the client-side process events whenever the process manipulates the record, changes the stage, or the status of the process changes to Active, Finished, or Aborted. 
The formContext.ui object includes formContext.ui.process that provides methods to interact with the form`s business process control.
All other options are incorrect.
