Please select items that would help you with Power Apps components reusability.

Answer options:

A.Business process flow
B.Power Apps component framework
C.Publisher components
D.Component Library
E.Canvas app components

Correct Answers: B, D and E 
The Components are reusable blocks that help you develop the Power Apps applications. Power Apps provides out-of-the-box standard controls (components) for creating applications, like HTML Text, Vertical Gallery, or Edit Form. However, Power Apps also offers tools to create and reuse the custom code components if your Power Platform solution requires more than standard controls. 
There are three types of reusable custom components: Canvas app components — these are components you can create within your canvas app and reuse them within the app.
Component Library — this is the library of the components you have access to and use for your apps. 
Power Apps component framework (PCF) — helps developers and app makers to create custom components.
PCF components can be used in all Power Apps applications: model-driven, canvas, and portal. In addition, you can package them into solutions and deliver them to the Dataverse environment. 
You can import and export components from the apps or store them in the Component Library. Using the Component Library to create, store, and distribute reusable components is the preferred collaboration and component standardization method. 
All other options are incorrect.
