You create a business recommendations rule for the field on your Power Apps app Input form. You don`t want the rule to work on Quick Create forms. 
What should be the scope of your rule?

Answer options:

A.All screens
B.Main form
C.Entity
D.Quick Create form
E.Input form

Correct Answer: E 
Microsoft Dataverse Business rules consist of three parts: conditions, actions, and scope. 
The scope of the rule is limited to the Entity, All Forms, and Individual Forms. 
An Entity level of Business rules actions includes Set column values, Clear column values, Set column requirement levels, Validate data and Show error messages. If your rule has an Entity scope, it will run two times: during the evaluation on all app`s forms and then when a record is saved. Also, the Entity scope has a global scope. The rule runs whenever a record is created or updated by any Power Platform products or API call. 
The All Forms scope makes sure that a business rule runs on all forms of your app, including Quick Create forms. The forms level has extra actions: Show or hide columns, Enable and disable columns, and Create business recommendations. 
If you need your rule to run only on one form, you need to be sure that it is the Main type. Then you can choose the form name (like Input form) from the Scope drop down in the Rule Designer and use the action that is limited to the forms. You will also be limited to model-driven apps because all canvas apps have only an Entity scope. 
All other options are incorrect.
